"He's out," Clippers coach Doc Rivers said. "He's not doing well enough."
Turkoglu, who is averaging 3.2 points and one rebound in 8.2 minutes per game this series, will be re-evaluated when the team returns to Los Angeles. However, he isn't expected to play this week.
The 35-year-old suffered the injury in Tuesday's Game 5 while defending Warriors forward David Lee in midair. Turkoglu was knocked to the ground as Lee picked up an offensive foul with 7:47 left in the third quarter.
As players tried to pick up Turkoglu after his injury, he brushed them off as he was writhing in pain during the duration of a timeout before being helped back to the locker room.
