School officials said Thursday that the younger Sanders, who had worn No. 12 this season, is changing to No. 21. The move comes after Gamecocks starting safety Jamyest Williams, who had been wearing 21 the past few seasons, decided to leave the team after four games. Williams will redshirt the rest of this season with the intent to transfer.
Shilo Sanders is a 6-foot-0, 190-pound freshman from Cedar Hill, Texas.
