The Boston Celtics have assigned rookie James Young to the Maine Red Claws. 

Young, a 6’6” guard/forward, has appeared in five games for the Red Claws this season and is averaging 22.4 points, 6.6 rebounds, 2.6 assists and 1.8 steals in 32.0 minutes per game, while shooting .458 (22-48) from beyond the arc. He recorded six points, one rebound and one block in six minutes for the Celtics against the Houston Rockets on November 1 and is averaging 2.2 points in 3.5 minutes per game in five contests with the team this season.

The Cleveland Cavaliers have recently been in contact with the Boston Celtics about their interest in facilitating a three-team trade.

The Cavaliers are seeking frontcourt depth and have specifically targeted Timofey Mozgov and Kosta Koufos.

The Celtics are aggressively pursuing future draft picks.

The Cavs cannot trade their own 2015 first-round pick because they already sent their 2016 pick to the Celtics in a previous deal. But they do own a protected Memphis first-rounder that they could trade.

The Cavs also posses a $5.2 million trade exception to use in a potential deal, which is one of the reasons they sought Mozgov and Koufos, as both of their contracts could fit into that exception.

The Boston Celtics had interest in acquiring Julius Randle from the Los Angeles in their trade discussions centered on Rajon Rondo. Randle is out for the season with a broken leg.

The Lakers have long sought to acquire Rondo from the Celtics.

Rondo was eventually traded to the Dallas Mavericks.

Brad Stevens made it clear that he is committed to his job as the head coach of the Boston Celtics, even as fans of the Indiana University Hoosiers speculate about Stevens returning home.

"I’ve committed to being here," Stevens said. "I’ve already left a situation once and that was the hardest thing I’ve ever had to choose to do. This is something that as long as they want me to be here, this is what I want to be doing and I’m going to give it everything I’ve got. I know it’s all specific to the rumor mills and the discussion of one spot. I think they’ve got a good coach who’s done a helluva job. He doesn’t deserve that speculation.

"I’m the head coach of the Boston Celtics. This is the job. This is where I am. This is what I want to do really well and I’m committed to being as good as I can every single day for the Celtics."

Stevens is in his second season as the Celtics' coach and has gained respect in the league.

Said Spurs coach Gregg Popovich: "He was a hell of a coach before he got here and he’ll be an even better coach as time goes on. He’s a special guy, that’s why Danny Ainge went and got him."

"I think Brad Stevens is an awesome coach," Kevin Love said. "They’re going to be able to figure it out as they accumulate more talent and like I said, I’m a big fan of Brad Stevens."

The Boston Celtics and guard Jameer Nelson have had preliminary discussions on his future role and "what if" possibilities before the February trade deadline, but buyout negotiations have not taken place yet, league sources told RealGM.

Nelson signed a two-year contract with the Dallas Mavericks last offseason, persuaded by the organization’s culture and an opportunity to start and compete for a Western Conference contender. Still, Dallas had scoured the market for an upgrade at point guard this season and acquired Rajon Rondo, ending Nelson’s brief tenure and sending him to a likely draft lottery team.

At 32, Nelson has cherished a role on a competing NBA team, but has now embraced his position with the Celtics. Over 11 seasons, Nelson is well-regarded as a professional and locker room voice.

Nelson spent his first 10 pro seasons with the Orlando Magic and started in his 23 games for Dallas. He’s averaged 12.4 points and 5.3 assists in his NBA career.

The Dallas Mavericks' pick in the Rajon Rondo trade is likely to be conveyed to the Boston Celtics in 2016.

The Mavericks' pick goes to the Celtics this season if it falls between No. 4 and No. 14. If the pick falls between eight and 30 in 2016, it will go to the Celtics.

The Dallas Mavericks and Boston Celtics have agreed upon a trade involving Rajon Rondo.

The Mavericks would send Brandan Wright, Jae Crowder, Jameer Nelson, one future first round pick and a future second round pick to the Celtics for Rondo and Dwight Powell.

"The deal is on course to happen tonight," said one source.

Adrian Wojnarowski reports the Houston Rockets have effectively dropped out of talks, with the Celtics focused on wrapping a deal with the Mavericks.

The Los Angeles Lakers offered the Boston Celtics multiple draft picks and Steve Nash for Rajon Rondo, according to sources.

The Celtics are in discussions with the Dallas Mavericks and Houston Rockets.

Rajon Rondo is open to re-signing with either the Dallas Mavericks or Houston Rockets should he be traded to one of those two teams, according to a source.

Given Rondo's looming unrestricted free agency, any deal would have to come with assurances that he'd be willing to re-sign with his new team.

Rondo is not actively seeking a trade from the Boston Celtics.

The Rockets will use their $8.4 million trade exception from the Jeremy Lin trade with the Lakers this past summer to acquire a player before Dec. 19 -- the deadline for acquiring players who can be dealt again on Feb. 19 under league rules. 

The Dallas Mavericks and Houston Rockets have engaged with the Boston Celtics on Rajon Rondo trade talks.

The Celtics have engaged on several fronts on Rondo with the Mavericks showing an increased interest. The Mavericks have a clear need at point guard.

Rondo is scheduled to be a free agent this offseason.

As of Thursday afternoon, Adrian Wojnarowski reported that the Mavericks have emerged as the frontrunner to trade for Rondo. Marc J. Spears reports that the Rockets are "still fighting" to acquire Rondo.

The Mavericks are offering Brandan Wright, Jae Crowder and a first round pick for Rondo.

Wojnarowski also reports that the Celtics have reached a point of no return on a Rondo trade.
