Oklahoma City guard Russell Westbrook left Friday's game against Toronto in the third quarter after appearing to injure his right knee.
Westbrook, who sat out Thursday's win at Cleveland to rest the knee that was surgically repaired earlier this season, was injured when Toronto's Kyle Lowry collided with him on a pump-fake near the sideline with 7:37 left in the third quarter.
After being struck on the knee by Lowry's leg, Westbrook immediately turned and called timeout, bending over in pain.
