WALTHAM, Mass. -- The Boston Celtics signed rookie Jarrell Eddie on Thursday and will evaluate him in advance of Monday's mandatory roster trimdown with a likelihood that he will land with the Maine Red Claws of the NBA Development League.

Eddie, an undrafted 6-foot-7 swingman who spent much of training camp with the Atlanta Hawks, was with the team on Friday, but simply observed the start of practice alongside Maine first-year coach Scott Morrison.

The Celtics have the ability to funnel as many as four training camp cuts to their D-League affiliate. The team has already waived camp invites Tim Frazier, Rodney McGruder, and Christian Watford with the expectation that they will land in Maine. Erik Murphy, acquired last month from Cleveland was also waived and had potential to also join the Claws, but the addition of Eddie could indicate that one of the recently waived players will seek another opportunity.

"[Eddie is a] player that we’ve watched in college at Virginia Tech and he’s a player that we watched in his exhibition games with Atlanta," said Celtics president of basketball operations Danny Ainge. "He’s always been a player that’s been intriguing to us. We’re just going to evaluate him before training camp ends. He obviously won’t learn our stuff that quick, but we’ll put him through some workouts after practice and just evaluate him over the next couple days. That’s really all it is."

Added Ainge: "We’ll continue to evaluate him, wherever he plays, but we just want to take the time to evaluate him while we have some time right now."

The Celtics now have 17 players on their roster with Eddie the only deal that's nonguaranteed. Rosters must be trimmed to a league maximum of 15 players by Monday afternoon.

Ainge said he had no further update on recently acquired Will Bynum, who remains a likely casualty of a bloated roster if the team cannot otherwise maneuver before Monday.

Some other notes from Friday's session:

•Faverani of Seville: Ainge said he expects second-year center Vitor Faverani to return stateside with the team on Thursday. Faverani underwent a second knee surgery in Spain earlier this month and has done the initial part of his rehab there. Ainge said Faverani is being accompanied by a team trainer and Ainge's son, Austin, the team's director of player personnel (who doubles as a translator). "We’re trying to make the transition for [Favearni] easy coming back here and seeing what they are doing from a rehab standpoint over there," said Danny Ainge, before quipping, "I think they are enjoying the sunshine in Seville." Ainge wasn't certain on Faverani's timeline moving forward, but estimated that he'd need another two weeks to a month of rehab before being ready to return to practice.

• Playing it Smart: Celtics rookie guard Marcus Smart missed a second day of practice due to illness. Coach Brad Stevens said the training staff noticed Smart catching some sleep before Wednesday's game and they believe the illness might have started then (though he starred in the first half that night). "He played a great first half being sick, but we want him to get better," said Stevens. "It’s a long season and the most important thing is to be healthy on Monday." Stevens has suggested that Smart could start at point guard if Rondo is not healthy enough for Wednesday's opener.

• Morrison's Maine men: The Red Claws announced the hiring of two assistants on Morrison's staff on Thursday in Seth Cooper, a former assistant at Indiana University, and Nathaniel Mitchell, a graduate assistant at Fresno State last season.
