Today is January 15th, which means that a number of players who had been ineligible to be traded until this point are now free to be moved by their respective teams. As Chuck Myron of Hoops Rumors outlined last month, Eric Gordon, Brook Lopez, Kris Humphries, Ersan Ilyasova, and Jeff Green are among the players who weren't eligible to be dealt until today.

However, in addition to rules that keeps players from being traded until December 15th or January 15th, the CBA also includes a stipulation that a team must have a player on its roster for three months before being able to trade him. That means guys who have signed contracts since October 15th are still ineligible to be dealt.

Here are the players who can't be traded quite yet, along with the dates they'll become trade-eligible:

Leandro Barbosa (Celtics): January 18th
Daniel Orton (Thunder): January 31st
Shaun Livingston (Cavaliers): February 15th

Because the trade deadline arrives on February 21st, players signed after November 21st won't become trade-eligible until after the season. Here are the guys who fit that description:

Jeff Adrien (Bobcats)
James Anderson (Rockets)
Patrick Beverley (Rockets)
Daequan Cook (Bulls)
Kevin Jones (Cavaliers)
Mickael Pietrus (Raptors)
Garrett Temple (Wizards)

In addition to recent signees, players who were claimed off amnesty waivers last July are also ineligible to be traded until July 2013. Some amnesty victims, like Andray Blatche, cleared waivers without being claimed and signed new contracts, so they're trade-eligible now, but the following players can't be moved this season:

Elton Brand (Mavericks)
Brendan Haywood (Bobcats)
Luis Scola (Suns)

Finally, players on 10-day contracts, such as Dominic McGuire, Maalik Wayns, and Josh Harrellson, also won't be trade-eligible at any point this season, even if they eventually receive rest-of-season contracts.

The Bobcats have signed Jeff Adrien and waived Cory Higgins, the team announced via press release. Higgins' non-guaranteed deal minimum-salary deal was to have become guaranteed if the team had kept him on the roster beyond today. Terms of Adrien's deal were not disclosed, but I'd assume Adrien will be on a minimum deal as well.

Ironically, they'll be paying more for Adrien, who's a two-year veteran, than for Higgins, who only has one year of experience, so I'd imagine Adrien's deal isn't guaranteed either. That would allow the Bobcats to cut Adrien later without committing to his full salary for the rest of the season, as they would have been forced to do if they kept Higgins past today.

Higgins is the son of Rod Higgins, Charlotte's president of basketball operations. The younger Higgins averaged 3.7 points in 10.3 minutes per game over the past two seasons for the Bobcats. The 6'7" Adrien was with Charlotte in training camp, but the team cut him only a few days in. He's appeared in 31 NBA games with the Rockets and Warriors the last two seasons, averaging 2.5 points and 2.6 rebounds in 8.4 minutes per contest.

Adrien had been playing with the Rio Grande Valley Vipers of the D-League, averaging 17.6 PPG and 11.2 RPG in five games so far this year. The Bobcats roster remains at 14 players, one short of the limit.

The Bobcats have waived Jeff Adrien and Paris Horne, according to Rick Bonnell of the Charlotte Observer (via Twitter).  Both players were signed to non-guaranteed, make-good contracts in September.  Charlotte's roster now stands at 16.

Adrien, 26, saw limited playing time with the Warriors in 2010/11 and the Rockets in 2011/12.  The UConn product reportedly drew interest from the the Rockets, Clippers, Lakers, Spurs, and Celtics before agreeing to terms with the Bobcats.  The forward also spent time with Orlando's Summer League team in 2010, though there was obviously different personnel in place.

Horne, 25, spent last season in Germany with BG Gottingen.  The 6'3" guard out of St. John's made a strong impression on the Bobcats as a member of their Summer League team this year but was unable to crack the final 15.  Bonnell notes that Horne was an intriguing player due to his quickness but was still a longshot to hang on.

The Bobcats have officially signed four players to their training camp roster, according to Rick Bonnell of the Charlotte Observer (via Twitter). Bonnell first reported a week ago that Jeff Adrien, DaJuan Summers, Paris Horne, and Josh Owens were expected to receive non-guaranteed, make-good contracts from the Bobcats.

Adrien, a UConn product, received limited playing time for the Warriors in 2010/11 and the Rockets in 2011/12. He reportedly drew interest from the the Rockets, Clippers, Lakers, Spurs, and Celtics before agreeing to terms with the Bobcats. Summers, who also has previous NBA experience, was drafted 35th overall in 2009 and has since played for the Pistons and Hornets. The 24-year-old forward has averaged 3.4 PPG in 81 career contests.

Horne, a 6'3" guard, played in Germany last season after graduating from St. John's in 2011. Owens, a 6'9" forward out of Stanford, was eligible for this year's draft and was ranked as a top-100 prospect by ESPN.com's Chad Ford, but went undrafted. Both players were part of the Bobcats' summer league squad.

The additions bring Charlotte's training camp roster to 18 players, including 13 on guaranteed contracts. Besides the four new additions, Cory Higgins was also re-signed to a non-guaranteed two-year, minimum-salary contract by the Bobcats earlier this month. Higgins, Adrien, Summers, Horne, and Owens figure to be fighting for the final two available roster spots over the next few weeks.

4:44pm: The Bobcats have agreed to terms with Adrien on a non-guaranteed contract, tweets Marc J. Spears of Yahoo! Sports. According to Spears, the Rockets, Clippers, Lakers, Spurs, and Celtics also showed interest in the forward.

3:53pm: Looking to bring at least 17 players to their training camp, the Bobcats are finalizing agreements with a handful of players expected to compete for a spot on the team's roster. According to Rick Bonnell of the Charlotte Observer, Paris Horne, Josh Owens, Jeff Adrien, and DaJuan Summers are expected to be added to the Bobcats' roster in the near future.

Horne, 25, played in Germany last season after graduating from St. John's in 2011. He's a 6'3" guard. Owens, a 6'9" forward out of Stanford, was eligible for this year's draft and was ranked as a top-100 prospect by ESPN.com's Chad Ford, but went undrafted. Both players were part of the Bobcats' summer league squad.

Adrien and Summers both have previous NBA experience. The 6'7" Adrien, a UConn product, received limited playing time for the Warriors in 2010/11 and the Rockets in 2011/12. Summers, meanwhile, was drafted 35th overall in 2009 and has since played for the Pistons and Hornets. The 24-year-old forward has averaged 3.4 PPG in 81 career contests.

If the Bobcats finalize deals with these four players, they're likely to be non-guaranteed contracts. With 13 Charlotte players on guaranteed deals, there could be a roster spot or two available on the team for players who impress in training camp.

Some notes from around the league on Friday night:

• Andy Vasquez of The Record reports that Brook Lopez may make his 2011/12 season debut tomorrow against the Bulls. Lopez has not played this year and is often mentioned as the centerpiece of a potential Dwight Howard deal for the Nets.
• The proposal is in place for a new NBA arena in Seattle, but the AP's Tim Booth points out that there are still hurdles to be cleared before the plan can progress.
• Stephen Jackson tells HoopsWorld's Alex Kennedy that he is frustrated with his playing time in Milwaukee and does not foresee sticking around with the Bucks long-term.
• Journeyman Jeff Adrien, who has bounced around the Warriors, Rockets, and D-League since 2010, has signed a deal to play in Russia with Khimki Moscow.

As we await the next wave of Linsanity tonight at Madison Square Garden, let's check out a few links from around the league:

• Kevin Martin, who was nearly traded to the Hornets in December, is unhappy about his role with the Rockets, writes Jonathan Feigen of the Houston Chronicle.
• After being waived by the Rockets, Jeff Adrien is drawing overseas interest, according to Sportando. However, the 26-year-old forward prefers to continue pursuing an NBA roster spot.
• Adding a point guard before the trade deadline isn't necessarily a priority for the Kings, says team president of basketball operations Geoff Petrie. Jason Jones of the Sacramento Bee has the details.
• Speaking of the Kings, a city council vote last night helped moved plans for Sacramento's new arena forward, reports Ryan Lillis of the Sacramento Bee.
• Inspired by Jeremy Lin's recent run, Bruce Arthur of the National Post looks back at six NBA veterans who had successful careers after going undrafted.

February 10th marks the day that all players on non-guaranteed contracts will have their deals guaranteed for the remainder of the season. However, if a team wants to meet that Friday deadline, it will need to make its decisions today, allowing its player(s) to pass through waivers in time.

Some non-guaranteed players, such as DeJuan Blair and Jeremy Lin, are in no danger of being waived. However, with a few dozen players on non-guaranteed deals across the league, there will be plenty of cuts before the day is out. Some of those players will sign 10-day contracts shortly after being cut, while others could join the D-League or find a place on our list of current unrestricted free agents.

We'll track all the day's decisions on non-guaranteed contracts right here, with the latest news up top:

Congratulations to Paul Pierce, who moved past Larry Bird on the Celtics' list of all-time leading scorers in tonight's win over the Bobcats.  Pierce, with 21,797 points, is now second only to John Havlicek, who retired in 1978 with 26,395 points across his 16-year career.  Here's a look at tonight's links..

• Suns guard Steve Nash should seek a trade to a contender, opines Eric Koreen the National Post.  Nash is a free agent at the end of the season and Phoenix could potentially lose him while getting nothing in return.
• It's possible that the Nuggets could look for some outside help as Danilo Gallinari could miss up to a month with an ankle injury.  Gallinari hopes to come back sooner, writes Benjamin Hochman of The Denver Post.
• If his Zalgiris Kaunas squad doesn't qualify for the Euroleague Top 8, then Sonny Weems writes (for HoopsHype) that he'll likely return to the NBA.
• Within his article regarding the Celtics' interest in Pau Gasol, Eric Pincus of HoopsWorld writes that multiple sources say that the J.R. Smith is looking for an opportunity to showcase his talents and be a primary option on offense.  This could make teams such as the Lakers, Clippers, Knicks, and Pacers poor fits for the 25-year-old.
• Veteran point guards Steve Nash and Jason Kidd are going to be in high demand on the open market this summer, tweets Chris Mannix of SI.com.
• The timing of Jeff Adrien's release from the Rockets may seem odd, but it was the only way that the club could sign Greg Smith before the center was scooped up by another team, writes Jonathan Feigen of the Houston Chronicle.  Adrien pulled down nine rebounds in just 17 minutes of play Monday night against Denver.
