Andrew Bogut went out in the first half of Monday's game against Charlotte with a right knee injury and did not return.
There was no immediate word on the severity. The 7-foot center walked off on his own, but with a significant limp.
He hurt the knee during a scrum for a rebound. The minute he fell backward, he clutched his right knee and pointed to the bench, indicating he wanted to come out of the game.
Bogut suffered a left knee injury that knocked him out of the NBA finals last season when he was with Golden State.
