Andre Roberson suffered a ruptured left patellar tendon during the third quarter of Saturday's win by the Thunder over Detroit.

Roberson was taken off the court on a stretcher after his left leg appeared to give out on the receiving end of an alley-oop attempt.

Roberson is expected to miss the remainder of the season and will undergo surgery.

"He's certainly a huge loss," Thunder coach Billy Donovan said after Saturday's game. "Everyone's been able to see that since he's kinda come back to us and what he's been able to do defensively. And he's found a way to be, offensively, a really effective player for us."
