Williams faces surgery after hurting the anterior cruciate ligament in his right knee Saturday during preseason practice. Coach Ron Zook said Williams is expected to take a medical redshirt and return next season.

The 6-foot, 292-pound Williams appeared in 12 of the IlliniÕs 13 games last season. Sophomore Josh Brent is expected to start at WilliamsÕ defensive tackle spot.
