Cook was charged with second-degree domestic violence. He was released on a $5,000 personal recognizance bond and has a court hearing date of Nov. 18, according to Richland County online court records. As a condition of his bond, Cook was ordered not to return to the location of the incident or have contact with the victim.
Gamecocks coach Will Muschamp said Sunday that Cook was dismissed and that was "all I'm going to say about that."
Cook is a 6-foot-4, 200-pound redshirt junior from Miami who sat out last season after transferring from Southern California.
Cook made one tackle this season against Charleston Southern. He has not played in any of South Carolina's other six games.
