Humphries (knee) set for MRI

Boston Celtics forward/center Kris Humphries will undergo an MRI on an ailing right knee on Wednesday and will not accompany the team on its trip to play the Atlanta Hawks.

Humphries sat out Saturday's loss in Detroit with what the team termed a strained right patella tendon. He's battled knee issues at times this season and the current issue has lingered. Celtics coach Brad Stevens said it was too early to know if the injury will force the team to shut down Humphries for the remainder of the season.

"If he’s able to play, he’s going to play," said Stevens. "That’s just kinda the way we’ve approached it all year. We want to be cautious if he’s got an issue and clearly he’s not feeling good right now. Hopefully the MRI reveals that it’s nothing and he can play at least a couple more games throughout the rest of the season."

The Celtics have five games remaining including Wednesday's tilt with the Hawks.

Stevens is expecting to have starters Avery Bradley and Jared Sullinger available on Wednesday. Bradley has missed the last three games due to a strained right Achilles, while Sullinger bruised his left thigh on Saturday in Detroit.

Bradley practiced the past two days, while Sullinger took Monday off and returned to practice on Tuesday. Stevens said both "should be in good shape to go."

Sullinger said he got kneed trying to defend a Greg Monroe layup attempt in the second half of Saturday's loss, but consecutive days off left him feeling better before Tuesday's practice.

"[The thigh was] tight, real sore, so I took a couple days off," said Sullinger. " I’m doing better. ... Just trying to get ready for [Wednesday's] game."

Asked if he gave any thought to taking additional time off, Sullinger said: "No, one, it’s my second year, and, two, I want to finish the season out strong. There’s never been a quitter inside me. I want to finish this season out."
