Coach Steve Spurrier says starting defensive end Cliff Matthews could miss up to three weeks with a shoulder injury.
Matthews dislocated his left shoulder in the first quarter of South Carolinas 31-13 loss at Tennessee last week. Spurrier had said earlier that Matthews would not play this week at Arkansas.
Matthews, a junior who started all nine games this season, is tied for fourth on the team with 39 tackles, which leads all defensive linemen.
Hell be replaced in the starting lineup by freshman Devin Taylor.
