USC All-American defensive lineman Leonard Williams suffered a high ankle sprain during Tuesday's practice, and one report says he will not be 100 percent for Saturday's Pac-12 game at Stanford.
The Los Angeles Daily News reported that Williams' sprain "will probably make him less than 100 percent against Stanford." After he was hurt, Williams was fitted with an ankle brace but did not finish practice.
Williams was named the best defensive player and the No. 3 overall player in the nation in College Football 24/7's top player countdown, and his presence will be huge as the Trojans look to stop Stanford's power-rushing attack. He can play both tackle and end, and had five tackles, an interception and two pass breakups in USC's season-opening rout of Fresno State.
His injury isn't the only one for the Trojans. Starting quarterback Cody Kessler missed practice entirely because of an issue with his toe, and starting guard Damian Mama dislocated his knee cap, which was put back in place.
"He scared himself more than anything else," coach Steve Sarkisian told reporters.
