After an 11-year NBA career, Cuttino Mobley announced his retirement in December 2008 when he was diagnosed with hypertrophic cardiomyopathy, a heart condition. Although Mobley hasn't appeared in an NBA game in nearly five years, he'll be attempting to make a comeback this year, according to Alex Kennedy of HoopsWorld.

Kennedy reports that ASM Sports, an agency that represents Kevin Garnett, Serge Ibaka, and Jeff Teague, among others, is holding a workout on May 31st for their draft prospects and veteran free agents. Mobley is one of a handful of veteran ASM clients expected to participate in drills and five-on-five scrimmages that day. According to Kennedy, Josh Howard, Rasual Butler, and Christian Eyenga are among the other free agents who will be in attendance.

It will be an uphill battle for Mobley, who will turn 38 before the 2013/14 season begins. I'd be surprised if he lands a spot on an NBA roster, but he did demonstrate exceptional scoring ability during his 11-year career. In 747 total contests for the Rockets, Clippers, Magic, and Kings, Mobley averaged 16.0 PPG to go along with shooting percentages of .433/.378/.835.

Three more former NBA players are headed to the D-League as they attempt to work their way back into the NBA, according to ESPN.com's Marc Stein. Stein reports (via Twitter) that Hilton Armstrong will join the Santa Cruz Warriors, Rasual Butler will join the Tulsa 66ers, and Josh Boone will join the Iowa Energy.

Armstrong, 28, was drafted 12th overall in 2006 and played in parts of five NBA seasons for the Hornets, Kings, Rockets, Wizards, and Hawks. The big man averaged 3.1 PPG and 2.6 RPG in 277 career contests, last playing in the NBA during the 2010/11 season. He'll join a Santa Cruz team that's fully owned and operated by Golden State.

Butler, who began his NBA career with the Heat in 2002/03, has averaged double-digit points three times and played in 638 NBA games, but was waived by the Raptors last season after appearing in 34 games for Toronto. The 33-year-old is headed for a 66ers squad that's owned and operated by the Thunder.

Boone, the Nets' 23rd overall pick in 2006, played four seasons with New Jersey, but hasn't played in an NBA game since his rookie scale contract expired in 2010. The former UConn big man averaged 5.2 PPG and 4.9 RPG in his career, and will join an Iowa Energy team that's shared as an affiliate by four NBA teams.

All three veterans will remain NBA free agents, free to sign with any team if they impress in the D-League.

A few Monday afternoon odds and ends from around the NBA:

• Marquis Daniels, Rasual Butler, and Rodney Carney were among the free agents in attendance at a workout hosted by the Bucks, according to Charles F. Gardner of the Milwaukee Journal Sentinel.
• Hasheem Thabeet spoke to John Rohde of the Oklahoman about the opportunity he has with the Thunder this season to earn playing time and reach his potential.
• Gary Dzen of the Boston Globe takes a look at Dionte Christmas, who he believes has a good chance to make the Celtics' roster with a strong training camp.
• Despite rumblings that the Grizzlies might be eyeing Michael Redd, Ronald Tillery of the Memphis Commercial Appeal says Memphis hasn't expressed any interest in the veteran two guard.
• Assistant coaches Lloyd Pierce and Bob Thornton have verbally agreed to one-year deals with the Grizzlies for the coming season, tweets Tillery.
• Michael Scotto of RealGM.com spoke to Reggie Williams, who is entering a contract year with the Bobcats, about Williams' improbable path to the NBA.

A few Tuesday afternoon odds and ends from around the NBA:

• After reporting yesterday that Dwight Howard still wants to be traded out of Orlando, Chris Sheridan of SheridanHoops.com outlines why the Nets and Knicks may be the most logical trade partners for the Magic.
• If Howard is dealt this summer, it's probably bad news for the Mavericks, writes Jeff Caplan of ESPNDallas.com. The Mavs could have the cap space for Howard next summer, but don't have the trade chips to get him right now.
• In an Insider piece for ESPN.com, David Thorpe examines some potential landing spots for Jeremy Lin, concluding that the Raptors, Nets, and Suns might be the best fits besides the Knicks.
• Rasual Butler has heard from several teams and plans to be ready to sign in July, according to Steve Kyler of HoopsWorld. The Raptors released Butler in March, in time for him to catch on with another team for the postseason, but the 33-year-old didn't sign another contract before season's end.
• In an interview with Gazzetta.it, Marco Belinelli said he expects to receive offers from the Hornets and other NBA teams, and wants to determine where he'll sign before trying to join the Italian national team for the Olympics. Hat tip to Emiliano Carchia of Sportando for the translation.

With many playoff contenders plagued by health issues, including injuries to a handful of superstars, some teams may be thinking about adding an extra body for the postseason. There are plenty of young players available in the D-League, but for a club in need of one extra piece, a veteran with playoff experience may be the preferred candidate.

Listed below are a few free agents with extensive playoff experience who would still be eligible for the postseason if they signed with an NBA team today. Many of these players have been out of the league this season and are hardly sure bets to pick up where they left off, but for clubs with depth issues, they could be worth at least a look.

• Rasual Butler: The Raptors waived Butler last month in advance of the buyout deadline to allow him to catch on with a playoff team. Although the Bulls were thought to have some interest, Butler still hasn't landed another NBA job. The veteran forward has played in 30 postseason contests, including a handful with Chicago last season.
• Michael Finley: Having been out of the NBA since 2010, the 39-year-old Finley is probably a long shot to contribute much to a playoff team. But he was still working out for NBA squads this season, and has 129 career postseason games on his resumé. Finley appeared in the playoffs in 10 straight seasons from 2001 to 2010, averaging 11.8 PPG.
• Eddie House: The sharpshooter has appeared in 66 postseason games, with a good chunk of them coming for the 2008 champion Boston Celtics. House shot 42.6% from downtown in 35 playoff games in 2008 and 2009 for Boston. Last season, House was on the Heat's playoff roster, though his role and impact were reduced in Miami.
• Allen Iverson: Iverson racked up over 3,200 minutes played in 71 career playoff games, which included a run to the Finals with the 2000/01 76ers. Iverson has averaged a staggering 29.7 PPG in the postseason, including 24.5 PPG in his most recent playoff appearance, in 2008 with the Nuggets. We know AI still wants to play in the NBA, but it's probably too late in the season for any team to risk the sideshow that could accompany signing the former MVP.
• James Posey: After being amnestied by the Pacers prior to the season, Posey has yet to catch on anywhere, which is a little surprising. While his production had fallen off over the last two seasons, the forward still provides veteran leadership, having played in 65 postseason games in his career. Like House, Posey played a crucial role in the 2008 playoffs for the Celtics, averaging 22.0 minutes in 26 games for the eventual NBA champions.
• Joe Smith: The 36-year-old has appeared in 62 career playoff games, including brief action in five games for the Lakers last year. Still, Smith hasn't been a useful part-time contributor since the 2008/09 season, so it's questionable whether he has much left to offer a contender.
• Jarron Collins, Devean George, Morris Peterson, and Etan Thomas are among the other veteran free agents with multiple seasons of playoff experience.

Much of the NBA spent the evening with concerns about Celtics swingman Mickael Pietrus, who suffered a head injury during tonight's game with the 76ers and left the arena in an ambulance. It originally appeared Pietrus would spend the night in a hospital, as ESPN's Chris Forsberg and others reported, but apparently his injury, a concussion, will allow him to return home for the night, Forsberg tweets. Here's more from around the Association:

• Ira Winderman of the Sun Sentinel reports that Rasual Butler, who is drawing attention from the Bulls, would have gotten a look from the Heat at the beginning of the season had they not signed Shane Battier (Twitter link).
• Grizzlies owner Michael Heisley is out of the running to buy the Los Angeles Dodgers, but separate groups that include Magic Johnson and Nuggets owner Stan Kroenke remain in the hunt with a decision looming as soon as next week, according to Bill Shaikin of the Los Angeles Times. 
• Raptors backup point guard Jerryd Bayless shined while starter Jose Calderon missed games with injury earlier this month, and Alex Raskin of HoopsWorld argues the team should bring back the restricted free agent this summer and give him a larger role.
• Despite a loss to the Raptors tonight, the Knicks have been playing markedly better since Mike Woodson took over as coach, but that doesn't mean the team had quit on former coach Mike D'Antoni, Tyson Chandler says, according to Newsday's Al Iannazzone.
• Chris Tomasson of Fox Sports Florida tweets that the Pistons have offered retiring Ben Wallace a job for when he hangs up his sneakers, but Wallace is undecided on whether he'll take it.

Mike James' second 10-day contract with the Bulls expires at the end of the day, which will leave Chicago with two open roster spots if the team doesn't re-sign James for the remainder of the season. With an eye on the postseason, the Bulls are considering how best to make use of those two spots.

Adrian Wojnarowski of Yahoo! Sports reports that Chicago is a potential destination for Rasual Butler, who was waived by the Raptors today. Meanwhile, K.C. Johnson of the Chicago Tribune says (on Twitter) that landing a big man is still a priority for the Bulls.

The Bulls have been linked to Leon Powe and were also thought to have a little interest in Ronny Turiaf, but Turiaf quickly signed with the Heat upon clearing waivers. If Chicago decides to use its open roster spots, expect the club to add a shooting guard and a big, but as we heard earlier this week, the team's current players don't feel like an addition is a necessity.

The Raptors have waived Rasual Butler, the team announced in a press release. By releasing him today, the Raptors allow Butler to sign elsewhere and be eligible for the playoffs.

Butler, who signed with Toronto in December for the veteran's minimum, has played in 34 games for the club, averaging just 3.2 points and 1.9 rebounds in 13.3 minutes per game. The 31-year-old has a career-low .308 FG% (.273 3PT%) and has played just two minutes in March for the Raptors, his sixth NBA team.

The Raptors, who have also traded Leandro Barbosa and waived Anthony Carter this month, will reduce their roster to just 12 players after parting ways with Butler, so it wouldn't be a surprise if they added a player or two for the season's final few weeks.

Adrian Wojnarowski of Yahoo! Sports (Twitter link) first reported that the Raptors had agreed to waive Butler.
