As long as Varnado clears league waivers on Tuesday afternoon, he will be eligible to a sign a 10-day contract with Miami. The Boston Celtics waived Varnado on Sunday.

Varnado had played sparsely in five games for the Celtics after a call up from Sioux Falls of the Development League.

The Heat will work out former Denver Nuggets center Chris "Birdman" Andersen on Tuesday, league sources told Yahoo! Sports. Andersen took a physical for the Heat on Monday.

Varnado, 24, was a second-round pick of Miami in 2010, and has played overseas in Italy and Israel over the past two seasons. The Heat released him late in training camp in September, and he joined Sioux Falls, where he had averaged 14 points, 10 rebounds and 3.9 blocks in 10 games this season.

There's no framework of a possible deal in place, but the Grizzlies have expressed a strong desire that any package involving Gay include Suns forward Jared Dudley and future first-round draft picks, sources said.

In an effort to avoid paying luxury tax in the short term, as well as get off the $17.8 million and $19.3 million owed Gay in the 2013-14 and 2014-15 seasons, new Memphis management has aggressively shopped Gay. The Grizzlies have made proposals on Gay to several teams, front-office sources told Yahoo! Sports.

Heat president Pat Riley has been scouring the landscape to bolster a foundering frontcourt bench and appears to be intrigued with the possibility of discovering how much Andersen, 34, has left in his game.

The Heat released center Josh Harrellson on Monday and now have two open roster spots.

At his best, Andersen, who is 6-foot-10, was one of the NBA's most active and relentless bench contributors. His array of tattoos – covering him head to toe – helped make him one of the league's most popular characters.

Andersen played 32 games for the Nuggets last season, and ultimately was waived in July

Dropped out of the Cleveland Cavaliers' rotation, forward Omri Casspi, the NBA's first Israeli-born player, has requested a trade, league sources told Yahoo! Sports.

Casspi has shown significant flashes of promise in his young career, but he has become an afterthought for the struggling Cavaliers since missing five games with gastroenteritis in December. In 19 games, Omri Casspi is averaging 4.9 points and 2.5 rebounds per contest. (AP)

Cavaliers general manager Chris Grant has been making calls on possible deals for Casspi, but nothing has materialized. The request for a trade was made through Casspi's representatives with Creative Arts Agency (CAA), sources said.

Cleveland officials privately insist that no such request was made, but multiple league sources with knowledge say that CAA recently made the request. Per league rules, neither the agent nor Casspi can publicly make a trade request without being subject to league-mandated fines.

After starting 93 games in his first three seasons in the NBA, Casspi has played one minute for the Cavaliers since

After several years bouncing between Europe and the NBA, Brown, 28, has had a breakout professional season with Siena. Nevertheless, the franchise's financial issues may leave the organization open to a buyout of his contract, sources said. Several NBA teams have inquired about the possibility of signing him as a backup point guard.

Brown leads the Euro League with 21 points per game and averages nearly six assists. He delivered one of the Euro League's greatest offensive performances recently with 41 points in a victory over Fenerbache. Brown has been chosen the Euro League's player of the week three times this season.

To save money, Siena cut ties with several top European players before the season. Nevertheless, Brown has kept Siena in the playoff race with a 10-3 record and the best

Whether or not Carmelo Anthony returns from his hyper-extended knee on Tuesday, the plan remains for Stoudemire to come off the Knicks' bench. Anthony told reporters that he will test his knee in pre-game on Tuesday and then make a determination on returning to the lineup.

Stoudemire, 30, has been one of the NBA's elite power forwards and had come into training camp believing he had worked himself into the best shape of his professional career. Nevertheless, Stoudemire suffered a knee injury in October, underwent surgery on Oct. 21 and has been rehabbing the injury most recently in practices with the Knicks' D-League franchise in Erie and finally with the Knicks.

"We need him," Anthony told Yahoo! Sports' Marc Spears on Friday. "I know we are playing well, but the

"….The past two days I have been weighing all of my options as I try to continue my basketball career," Roy said in a statement released by the team. "I have decided to explore additional treatment options and an extensive rehabilitation plan.

"My goal has been, and continues to be, to return to the basketball court as healthy as possible in order to help our team."

After returning to practice for the first time since knee surgery on November 19th, Roy suffered a setback in recent days, and strongly considered forgoing the search for further treatment avenues and another long process of rehabilitation to instead retire, sources
