Swearinger is being punished for an illegal hit during the Gamecocks' 49-6 win over Alabama-Birmingham this past Saturday. He was called for a personal foul during the game for hitting UAB's Patrick Hearn on the helmet while breaking up a pass.
Swearinger, a senior, will miss the Gamecocks' game against Missouri this coming Saturday.
