With 5:30 remaining in the first, Rajon Rondo missed a 19-foot running jump shot, and Perkins went up for the offensive rebound, jockeying for position with the Lakers' Andrew Bynum. The Boston center crashed into Bynum, became entangled with him, and sprained his right knee as he fell to the ground.
Perkins left the game immediately and didn't return. Teammates Shelden Williams and Brian Scalabrine helped Perkins make his way to the Celtics' locker room, as he found it difficult to walk on his own power.
Perkins finished the game with zero points and one rebound in 6:30 of play.
According to Yahoo Sports' Adrian Wojnarowski, citing league sources, Perkins has sprained MCL and PCL ligaments in his knee.
The Celtics are unsure of Perkins' status for Game 7 of the NBA Finals against the Lakers on Thursday night. Coach Doc Rivers has said he's unsure whether Perkins will play, and if he doesn't, the coach is also unsure of whether Rasheed Wallace or Glen Davis will start in his place.
