SAN ANTONIO (AP) -- San Antonio Spurs All-Star Tim Duncan sprained his left knee and right ankle after getting tangled with an opponent and had to be helped off the court in the first half of Saturday night's game against the Wizards.
The severity of the injury was not immediately known, though the team announced it was a sprain and that Duncan would not return to the game.
Duncan lay on the court clutching his knee for a few minutes after Washington forward Martell Webster rolled into the back of it while fighting for a rebound. Duncan got up on his own, but limped to the locker room with the assistance of teammates Stephen Jackson and DeJuan Blair.
Duncan, who was listed as probable with a sore left knee, returned to the lineup after missing the team's past four games.
The 14-time All-Star is averaging 17.5 points and 9.8 rebounds per game this season.
