Mavs’ Dante Exum Undergoes Season-Ending Knee Surgery

December 12: Exum has undergone successful season-ending surgery, the Mavs announced on Friday (via Twitter).


November 20: Dante Exum‘s 2025/26 season has come to an end before it even began, according to the Mavericks, who announced today (via Twitter) that the veteran guard will undergo season-ending surgery.

According to the Mavs, Exum – who had yet to play at all this fall – has continued to deal with complications related to an offseason procedure on his right knee. It has been determined that a follow-up surgery is necessary to address the issue.

It’s the latest in a long line of injuries that have limited Exum’s availability over the course of his professional career. After playing all 82 games as a rookie, the former fifth overall pick missed his entire second NBA season in 2015/16 due to a torn ACL, then was plagued by shoulder, ankle, and knee issues in subsequent years.

Exum rebuilt his value by playing in Europe from 2021-23, then returned stateside during the 2023 offseason and has been in Dallas since then. The 30-year-old has been a very effective role player for the Mavs when healthy, averaging 8.0 points, 2.8 assists, and 2.4 rebounds in 19.5 minutes per game, with a shooting line of .516/.472/.768.

However, he has been made just 75 appearances since the start of the 2023/24 season, including just 20 in ’24/25 due to right wrist surgery and a broken left hand.

With the Mavericks’ front office very much in the news as of late, the team’s handling of Exum in recent months deserves some scrutiny, notes Grant Afseth of Dallas Hoops Journal (Twitter links).

As Afseth points out, the Mavs never publicly disclosed Exum’s offseason knee surgery before today and had to use the stretch provision to waive Olivier-Maxence Prosper‘s guaranteed $3MM salary in order to create enough room under their hard cap to bring back Exum on a guaranteed minimum-salary deal. Given Exum’s injury history, that was a risky move, especially considering that Dallas badly needed backcourt depth while Kyrie Irving continued to recover from his ACL tear.

While the Mavs could waive Exum to open up a spot on their 15-man roster, they won’t have enough room under that hard cap to sign a replacement until January, barring a separate cost-cutting move. If Exum remains on the roster, Dallas could apply for a disabled player exception, but it would be worth just half of the guard’s salary, making it too small to be of much real use.

Concerns About Aprons, Depth Making Teams Warier Of Highly Paid Vets

As teams around the NBA weigh potential trades or signings that would add a maximum-salary (or near-max) veteran to their roster, they’ve become increasingly wary of navigating the tax aprons, as well as maintaining enough flexibility to build a deep roster, according to executives who spoke to ESPN’s Brian Windhorst and Tim Bontemps.

“There are two major shifts happening,” a Western Conference general manager explained to Windhorst. “We have everyone being very mindful of the aprons and carefully slotting their players to fit. Then you have the nature of the game, where you need deep rosters to play this volume of games at the speed the league is playing.”

Stars are still considered vital to building a championship-caliber roster, Windhorst writes, but front offices are more concerned than ever about the potential availability of a player who will be earning upwards of 30-35% of the salary cap, as well as the cost of acquiring and retaining that player, in terms of either salary, draft picks, or both.

“The max-level guys who make tons of money can’t play as many minutes as they could before, so they become less valuable,” an Eastern Conference executive told Bontemps. “You can’t be committing that much of your money to guys who won’t play at all or cannot sustain the same number of games and minutes.”

“You just can’t paper over a guy on your roster that isn’t delivering value at the highest levels,” another Eastern exec added, per Bontemps. “You can manage missing the lower-end guys, but the long-term salaries making $30, $40, $50 million? There’s no getting over that. Those guys bury you in this system.”

Windhorst recently broached this topic in an episode of The Hoop Collective podcast, expressing some skepticism that there will be teams willing to make massive offers for Bucks forward Giannis Antetokounmpo. However, in today’s ESPN article, Windhorst acknowledges that Antetokounmpo – a two-time MVP who is on the wrong side of 30, is on a super-max contract, and will likely warrant another huge extension in the near future – is among the potential exceptions, writing that the “old rules” still apply to a player of that caliber.

“I don’t think you’d see 29 teams make an offer like if, say, Victor (Wembanyama) was available, but there would be plenty of interest (in Antetokounmpo) and probably two to three teams would be willing to go all-in right now,” an East executive told ESPN. “Every player has risk, and he’d have some risk, but this is one you don’t have to work too hard to talk yourself into.”

Conversely, Mavericks big man Anthony Davis, whose 2025/26 salary is identical to Antetokounmpo’s and who is a year-and-a-half older, is the sort of player whose market would be less robust due to concerns about his availability and the percentage of a team’s cap he’d take up, says Bontemps.

“For a guy like Anthony Davis,” a Western Conference executive said, “it’s hard to justify them getting a 35 percent max when they aren’t playing a ton of minutes and games.”

Execs around the NBA may view Philadelphia as a cautionary tale. The Sixers are paying Joel Embiid and Paul George a combined $107MM this season — they’ve appeared in nine and eight games, respectively, and haven’t performed at their usual level.

Bontemps also points to Kings center Domantas Sabonis, Grizzlies forward Jaren Jackson Jr., and Jazz forward Lauri Markkanen as examples of players whose recent pay raises might make some teams less inclined to give up significant hauls for them if they were available. Sabonis will make $94MM in the two seasons after this one; Jackson has a four-year, $205MM extension starting in 2026; and Markkanen will make nearly $50MM annually through 2028/29.

“On their last contracts, they had good value,” an executive said of that trio. “(Now) they are all at a whole new threshold, where you look at them totally differently.”

While front offices may be proceeding with an abundance of caution on certain trade targets, that doesn’t mean that every star who ends up on the trade block will be available at a discount. Even for players with red flags, there could always be one team willing to make a more aggressive offer than what 28 others would consider rational. Still, Windhorst and Bontemps suggest this evolving league-wide sentiment is a factor that could impact the NBA’s trade market going forward.

“The aprons are causing people to think and act differently,” a scout told ESPN. “But there will always be teams that decide to strike while the irons are hot. … It’s an even bigger risk-reward calculation than it has ever been.”

Spurs Sign Kyle Mangas To Two-Way Deal, Waive Riley Minix

The Spurs have signed guard Kyle Mangas to a two-way contract, according to NBA.com’s transaction log. Two-way forward Riley Minix was waived in order to make room on the roster for Mangas, Michael Scotto of HoopsHype reports (via Twitter).

Mangas, who went undrafted out of Indiana Wesleyan in 2021, has signed non-guaranteed Exhibit 10 contracts prior to each of the last three seasons, but has yet to appear in an NBA game. Since going pro, the 6’4″ guard has played in the Czech Republic, Lithuania, Canada, and the G League.

Mangas has been playing this fall for the Austin Spurs, San Antonio’s NBAGL affiliate. In 10 games, he has averaged 18.5 points, 5.0 assists, 2.9 rebounds, and 1.5 steals in 35.8 minutes per contest, with a strong shooting line of .500/.411/.727.

Minix had also been playing well at the G League level, with averages of 15.5 PPG, 6.4 RPG, and 3.3 APG on .463/.394/.813 shooting in 11 games for Austin. However, the 25-year-old has only made four total NBA appearances for the Spurs since first joining the team on a two-way contract during the fall of 2024.

Mangas joins David Jones Garcia and Harrison Ingram as the two-way players on the Spurs’ roster. As our tracker shows, he’ll be eligible to be active for up to 35 NBA games on his new two-way deal.

Spurs’ Wembanyama Expected To Return On Saturday

Spurs star Victor Wembanyama is expected to return to action on Saturday for the team’s NBA Cup semifinal matchup with Oklahoma City, per ESPN’s Shams Charania (Twitter link). San Antonio has officially listed Wembanyama as probable to play.

Wembanyama has missed the Spurs’ past 12 games due to a left calf strain he sustained on November 14. However, there was a sense this week that he was in the final stages of his recovery from that injury.

Asked after his team’s NBA Cup quarterfinal win on Wednesday whether there was a chance Wembanyama could be back for the semifinal, head coach Mitch Johnson replied, “Very much so.”

Wembanyama, who will turn 22 in January, was playing at an MVP-caliber level prior to his injury, averaging 26.2 points, 12.9 rebounds, 4.0 assists, and 3.6 blocks in 34.6 minutes per game as San Antonio won eight of its first 12 games.

Despite losing their defensive anchor, the Spurs have remained firmly in the thick of the Western Conference playoff picture by going 9-3 in his absence. At the time of Wembanyama’s injury, the Spurs ranked 12th in the NBA in offensive rating and sixth in defensive rating. Since November 15, the team has the league’s 20th-best defense but the sixth-best offense.

Barring a late setback for Wembanyama, it appears as if Saturday will be the first time that the Spurs have De’Aaron Fox, Stephon Castle, Dylan Harper, and Wembanyama active for the game game. Whether that will be enough to topple the 24-1 Thunder and earn a spot in Tuesday’s NBA Cup championship contest remains to be seen.

And-Ones: Marjanovic, NBA Cup, Under-25s, FAs, Collins

Former NBA center Boban Marjanovic has signed with KK Ilirija, the Slovenian team announced in a press release.

Marjanovic, 37, made his NBA debut with San Antonio in 2015 and spent nine seasons in the league, appearing in 331 total regular season games for the Spurs, Pistons, Clippers, Sixers, Mavericks, and Rockets. After playing for Houston in 2023/24, he split last season between Fenerbahce in Turkey and the Zhejiang Lions in China.

Marjanovic’s new team competes in Slovenia’s domestic league and the ABA League, but isn’t part of the EuroLeague.

Here’s more from around the basketball world:

  • How do players and coaches around the league feel about the NBA Cup? Most of the ones who spoke to The Athletic’s staff about the tournament offered positive feedback, with Bucks head coach Doc Rivers referring to it as “a  benefit” for the league, while Timberwolves head coach Chris Finch called it a “perfect shot in the arm” for the first half of the season. “I think everybody’s taking it pretty serious, with what the stakes are, what the rewards are,” said Stephon Castle, whose Spurs advanced to the semifinals. “And again, being able to play in big-time games, it just amplifies the regular season a little bit.”
  • Spurs big man Victor Wembanyama took the No. 1 spot in ESPN’s list of the top 25 players under 25 years old, just ahead of Minnesota guard Anthony Edwards and Detroit guard Cade Cunningham. San Antonio, which also has Castle and Dylan Harper in the top 25, is one of four teams with three players on the list, along with the Rockets, Pistons, and Magic.
  • Eric Pincus of Bleacher Report ranks the top 20 free agents currently on the market, with Malik Beasley, Ben Simmons, and Tristen Newton leading the way. Newton has only played 16 total minutes in eight NBA appearances, but he’s averaging 26.3 points and 8.1 assists per game in the G League this fall.
  • Former NBA center Jason Collins, whose family announced in September that he was being treated for a brain tumor, has revealed that he has Stage 4 glioblastoma, a deadly form of brain cancer. Collins, who told his story via Ramona Shelburne of ESPN, said the average prognosis for his condition is just 11 to 14 months.

Central Notes: Giannis, Bucks, Cavs, Pistons, Duren

While trade speculation surrounding Giannis Antetokounmpo has picked up again this month, a number of rival executives around the NBA believe there may not be resolution on the Bucks star until the offseason, writes Sam Amick of The Athletic.

The outlook on Antetokounmpo could change if he makes an explicit trade request ahead of the February 5 deadline, Amick acknowledges, but he notes that teams would be better positioned to make a blockbuster deal during the summer, when they have more cap and roster flexibility and there’s less mystery surrounding draft picks.

Asked this week about the rumors swirling around his teammate, Bucks guard Kevin Porter Jr. referred to them as “false information,” per Eric Nehm of The Athletic (Twitter link).

“At the end of the day, everyone needs to wait until Giannis says something,” Porter said. “Because all this is just he say, she say, and I guarantee when we start winning as we go 8-0, 9-0, you won’t see nothing about the Bucks. You won’t see, ‘Oh, the Bucks are 8-0, 9-0, they’re flourishing and Giannis is…’ We’re not going to see any of that positive news. So at least for me, this is the last time I’m going to answer anything false.”

We have more from around the Central:

  • The Bucks, who vowed during their four-day layoff to remain competitive and get back in the playoff picture with Antetokounmpo inactive, backed up those comments on Thursday with a 116-101 win over Boston. After scoring 31 points in that game, Kyle Kuzma said the 11-15 team still has plenty of work to do, according to Nehm. “We gotta do it again,” Kuzma said. “This all does not mean anything if we come out soft (the next game). If we come out not playing hard, then we’re two steps back. … Be aggressive, both ends.”
  • The Cavaliers have had five days off since losing to Golden State last Saturday, but that hiatus was hardly a vacation. As Chris Fedor of Cleveland.com (subscription required) details, the team – which is off to an underwhelming 14-11 start – held an “uncomfortable” film session on Tuesday in which head coach Kenny Atkinson didn’t hold back his criticism. “He just called us out,” forward De’Andre Hunter said. “He broke down exactly what we needed to do, exactly what we haven’t been good at. We watched it. As a whole team, it’s not the easiest thing to see when you’re not doing well, but we saw a lot of that. It was definitely a tough, tough, hard film session. But I think we needed it. I think it’s gonna help us in the long run.”
  • In a mailbag for Pistons.com, Keith Langlois explores whether there’s room in the Pistons‘ rotation for Marcus Sasser, considers what Jaden Ivey‘s role will look like going forward, and explains why he’s dubious about the idea that Detroit would make a real play for Anthony Davis this season.
  • Esfandiar Baraheni of The Athletic (video link) breaks down film to explain how center Jalen Duren has emerged as the Pistons‘ second star ahead of his restricted free agency in 2026.

Western Rumors: Kings, Wolves, White, Mavs, Murphy, Kuminga

Moving Zach LaVine‘s maximum-salary contract without attaching a draft pick as a sweetener could be a challenge for the Kings, according to Sam Amick of The Athletic, who suggests that Sacramento general manager Scott Perry views the team’s draft assets as a valuable part of a potential rebuild and isn’t inclined to move them.

With that in mind, Amick suggests there’s a “very real chance” that LaVine and other Kings veteran trade candidates, including Domantas Sabonis and DeMar DeRozan, stay in Sacramento beyond this season’s trade deadline. As Amick points out, Perry has preached patience as he attempts to turn the Kings’ roster into one capable of contending.

League sources tell The Athletic that Sabonis has “heeded that call” for patience and is prepared to remain in Sacramento for the foreseeable future. The Wizards, Suns, and Bulls are among the teams that have had interest in Sabonis in the past and could still be suitors, according to Amick, but like LaVine, the veteran center won’t be easy to move due in part to his sizable contract.

Outside of the Kings’ veteran stars, guard Keon Ellis continues to be the trade candidate who holds the most intrigue around the NBA, but the team hasn’t ruled out the possibility of hanging onto Ellis and working out an extension when he becomes eligible for one later this season, Amick writes. While that may be the case, I have to think that Ellis would have a more consistent role in Sacramento’s rotation if that path is really the team’s preferred outcome.

Here are several more trade-related items of interest from around the Western Conference:

  • A team source confirmed to The Athletic that the Timberwolves have interest in Bulls guard Coby White, as was reported on Thursday. However, because White will likely be in line for a significant raise in the offseason, the Wolves may view him as a potential rental, which would make them less inclined to give up the sort of return Chicago would be seeking, Amick explains.
  • While many NBA observers were anticipating a fire sale in Dallas following the Mavericks‘ slow start, one league source who spoke to Amick said there have been some indications that the Mavs are still mulling the possibility of pursuing upgrades on the current core this season rather than becoming a deadline seller. As Amick points out, Dallas is technically in a play-in spot right now at No. 10 in the West, so if the team expects to get Kyrie Irving back from his ACL tear in the coming months, the idea of making a postseason push isn’t outlandish.
  • While the Warriors have long had interest wing Trey Murphy III, Amick has gotten “mixed” feedback on what the Pelicans think of Jonathan Kuminga, who would likely be a salary-matching piece in any Golden State offer for Murphy.
  • Meanwhile, while Dalton Johnson of NBC Sports Bay Area tweeted earlier this week that the Suns are still a potential suitor for Kuminga, John Gambadoro of Arizona Sports 98.7 reports (via Twitter) that Phoenix’s level of interest in the Warriors forward has dropped since the offseason. Part of what appealed to the Suns when they considered Kuminga during the offseason was the idea of getting him on a four-year contract, Gambadoro explains, so acquiring him on his current short-term deal holds less appeal.

Heat Not Planning To Fill 15th Roster Spot In Short Term

As of Saturday, the Heat will have the ability to fill the open spot on their roster  by signing a free agent to a prorated minimum-salary contract without surpassing the luxury tax line. However, a league source tells Anthony Chiang of The Miami Herald that the club isn’t expected to immediately add a 15th man in the coming days.

As Chiang writes, Miami would prefer to retain roster and cap flexibility for potential pre-deadline trades and/or late-season signings. The team is relatively whole right now, with only Pelle Larsson (ankle sprain) and Terry Rozier (on leave following his arrest in a federal gambling case) unavailable, so a 15th man likely wouldn’t have a regular role anyway.

The Heat are currently operating $1,606,363 below the luxury tax line, while the cap hit for a minimum-salary free agent signed on Saturday would be $1,596,834. That number will continue to decline by more than $13K every day, so Miami could maintain more breathing room below the tax threshold by waiting until later in the season to sign a free agent. Not filling that roster spot would also allow the Heat to take back up to about $1.6MM in salary in a mid-season trade without becoming a taxpayer.

The tax line isn’t a hard cap, so the Heat could surpass it now and attempt to duck back out of tax territory later in the season. However, that approach carries some risk, since the team would need to rely on a trade or buyout to shed salary. Avoiding the tax this season is a priority for Miami, Chiang writes, since the club wants to avoid repeater penalties in future years after finishing in the tax in each of the past two seasons.

It’s also worth noting that Rozier’s $26,643,031 salary is partially guaranteed for $24,924,126. Theoretically, that means the Heat could open up another $1.7MM+ below the luxury tax line by waiving Rozier on or before January 7, the league-wide salary guarantee date.

However, there are two potential complications. For one, the Heat haven’t received clarity from the NBA on whether they can trade or waive Rozier while he’s on leave as a result of his arrest in connection to an illegal gambling case, Chiang writes. And even if Miami were permitted to cut Rozier, the club would have to get back to the league-mandated minimum of 14 players on standard contracts within two weeks, which would eat into those $1.7MM in potential savings.

In related news, the Heat will have a representative in attendance next Wednesday at an arbitration hearing for Rozier, according to Ira Winderman of The South Florida Sun Sentinel (subscription required). The subject of hearing, which will involve the NBA and the players’ union, is whether Rozier should be paid while on leave. His withheld salary is currently being placed in an escrow-type account.

Stein’s Latest: Mavs, Davis, Bulls, Kuminga, CP3, Pelicans

Mavericks governor Patrick Dumont has begun gathering information on possible candidates to run the team’s front office on a permanent basis following last month’s ouster of Nico Harrison, reports Marc Stein of The Stein Line (Substack link).

However, according to Stein, Dumont is in no rush to complete that search process and is content with the idea of taking a committee approach for the rest of the regular season. While Michael Finley and Matt Riccardi are the team’s co-interim general managers, minority owner Mark Cuban, head coach Jason Kidd, and Dumont himself are also providing input on front office decisions, with Dumont having become “far more involved” since Harrison’s dismissal, per Stein.

One major decision facing that committee prior to this season’s trade deadline is whether or not to trade star big man Anthony Davis. Stein hears from sources that a Davis deal isn’t a foregone conclusion by any means. As Stein explains, the Mavs recognize that last season’s Luka Doncic blockbuster can’t be undone, so the team doesn’t want to just accept the best offer on the table for Davis. Accepting a subpar return for him would risk simply “compounding mistakes already made,” Stein writes.

Here’s more from Stein’s latest NBA round-up:

  • The Bulls don’t appear to have any real interest in Davis, but they remain a team to watch for Warriors forward Jonathan Kuminga, Stein says. As Stein notes, Chicago has conveyed some interest in Kuminga in the past, bringing him in past discussions involving Alex Caruso and other players.
  • The Hornets were among the teams with interest in Chris Paul during the offseason, but the veteran point guard wasn’t interested in playing so far away from his family in Los Angeles. According to Stein, Charlotte is no longer expected to pursue Paul at this time, but CP3 is believed to be more open-minded about destinations further removed from L.A. Paul, who remains under contract with the Clippers for now, will become trade-eligible on Monday.
  • Rookies Derik Queen and Jeremiah Fears are now viewed as the most untouchable players on the Pelicans‘ roster, Stein writes. That designation used to belong to Trey Murphy III and Herbert Jones — while New Orleans may be more open to listen on those players now, the team’s asking price for Murphy and Jones is still “extremely” high, according to Stein, who notes that the Pelicans are essentially discouraging inquiries based on the return they’re seeking.

Nets Notes: Porter Jr., Trade Talk, Traore, 20-Game Outlook

Michael Porter Jr. was traded by a former champion to a rebuilding club. The former Nuggets forward doesn’t mind playing for the Nets. In fact, Porter would prefer to stick around Brooklyn rather than be on the move again, he told Brian Lewis of the New York Post.

“Yeah, I love it here,” Porter said. “I love the staff, I love the energy of practice. Everyone gets along and has great vibes and great energy around the facility. So whatever team wants and appreciates what I bring to the table, then that’s where I want to be. And I feel like they do here.

“I don’t know their long-term plans; that’s above my pay grade,” he added. “But any good, successful team, you need a mix of young, developing guys with unlimited energy, and you need some older guys that have been there and done that and can hand it down and teach the young guys. So any team that thinks they’re going to win at a high level with only young players, it doesn’t really happen. But like I said, if they want me here, I’d love to be here.”

Porter Jr. has one season remaining on his contract after this one — he’s owed a guaranteed $40.8MM salary for 2026/27. He’s averaging a career-high 25.8 points, 7.6 rebounds and 3.2 assists per game.

Here’s more on the Nets:

  • As the NBA’s trade season approaches, head coach Jordi Fernandez hopes his players can block out the noise and worry about winning games and improving their skills. “It’s that part of the year and we all have to deal with it. It’s not the most enjoyable part of the year, but we love our guys,” Fernandez told Dan Martin of the New York Post. “We’re gonna keep focusing on working and getting better and competing. We cannot control anything on the outside, even though we know things may happen. … We’re not the ones thinking or talking [about trades]. We want work, we want accountability [and] we want competitiveness. That’s what we focus on.”
  • The Nets recalled this year’s No. 19 pick from their G League affiliate in Long Island on Thursday and Nolan Traore could jump right into the rotation. Traore posted averages of 18.8 points and 6.4 assists per game while shooting 43.1% from three-point range in 13 G League outings. “His superpower is speed,” Fernandez said of Traore, per C.J. Holmes of the New York Daily News. “He’s been shooting the ball very well and confidently, which I loved. He’s been trying to be more vocal, that’s what you want your point guards to be… And then the assist-to-turnover [ratio]. I think he struggled a little bit with the turnovers at times and how he reacted to those turnovers, which turnovers will happen, and I don’t care as long as you move on to the next play, and he’s had impressive numbers, assist-to-turnover ratio over his past three, four games, so, very happy with where he’s at.”
  • The Nets have won three of their last four games heading into their road matchup against Dallas on Friday. “We’re 23 games in and we’re looking at the next 20 games,’’ Fernández said, per Martin. “Can we sustain [it]? Can we get better? Then we look at the next 20. The process is the most important thing for us and the development of the group, not just one player.”
