Brad Stevens was on the radio earlier and mentioned that both Rajon Rondo and Avery Bradley were questionable for tonight's game.
Regarding Rondo:

"I don’t know how many games he’s played since January 17th but it’s been a few," Stevens continued, "You are going to have just fatigue and general soreness on his other muscles. I think it doesn’t look like he’ll play tonight, based on the early morning report that I got. We’ll hear final word when we get ready for our walkthrough."
On Bradley:
Avery will be determined later on tonight. It'll be a better chance than Rondo, but it's probably 50-50 he will play tonight," Stevens said.
I'm sure we'll get updates as we get closer to gametime.
