NORMAN, Okla. -- Oklahoma sophomore guard Willie Warren will have season-ending arthroscopic surgery on his injured right ankle.
The school said Warren will have the procedure Wednesday. Warren, last season's Big 12 freshman of the year, is the Sooners' leading scorer, averaging 16.3 points per game.
He initially injured the ankle during a practice Jan. 21 and missed two games. He re-injured it during Oklahoma's game at Colorado on Feb. 17. Warren has missed Oklahoma's last four games.
Oklahoma (13-16, 4-11 Big 12) has lost seven straight games, its longest losing streak since dropping eight straight during the 1968-69 season. The Sooners are in danger of posting their first losing season since the 1980-81 campaign.
