Jermaine O'Neal underwent arthroscopic surgery on his left knee on Friday and will need six to eight weeks to recover.

O'Neal has missed 32 games this season due to persistent soreness in his knee.

"I think [surgery] was the right decision," said coach Doc Rivers. "I wish we had moved a little earlier on it, but I think J.O. had to make sure he wanted to do it. And he exhausted every avenue, which I thought he should have done because it's a tough decision."
