"If he's ready to go, he'll play," Thunder coach Scott Brooks said. "If he's not, we won't play him. But we'll see how he feels. We have all day tomorrow. We have treatments today, treatments tomorrow and he'll be a game-time decision."
Perkins initially suffered the injury in the final game of the Thunder's first-round series against the Dallas Mavericks. With eight days off between series, Perkins was able to recover in time to play the Lakers.
But less than two minutes into the third quarter Monday night he went up for a dunk and grimaced on his way back down the court. Perkins came out of the game 15 seconds later and went back to the locker room to be examined.

Perkins returned to the bench and Brooks said Perkins could have played had the Thunder not held a comfortable lead.
"We'll see how he feels tomorrow," Brooks said. "One of the things that we know about Perk is that he's as tough as they come. If they would ever do an 'Avengers 2,' he would probably be one of the characters: 'Perk.' Thor, Captain America, Hulk and Perk.
"He's as tough as they come. He wants to play. But if he's not ready to play, we won't play him tomorrow."
Perkins averaged 5.1 points and 6.5 rebounds this season. He had four points, one rebounds and two blocks Monday.
Brooks said Nazr Mohammed would replace Perkins if he is unable to play.
