Gamecocks coach Will Muschamp said Dowdle will have the operation later this week, after he left in the second quarter of the team's 15-9 victory at Tennessee last Saturday. Dowdle becomes the latest significant South Carolina player sidelined by injury.
Wide receiver Deebo Samuel was injured last month and had surgery to repair a broken bone. He is holding out hope to return before the end of the year. Linebacker Bryson Allen-Williams is out for the season after shoulder surgery.
Dowdle, a 5-foot-11, 220-pound sophomore from Asheville, North Carolina, was the Gamecocks' top rusher last season. He has gained 206 yards on 60 carries this season.
