Defensive back Kadetrix Marcus (6-1 190) of Stone Mountain, Ga., committed Sunday night to South Carolina.
Marcus had been favoring the Gamecocks over Tennessee, South Florida and West Virginia.
He did not make it in for the Arkansas game but contacted recruiter Lorenzo Ward to make his pledge.
Marcus made two unofficial visits earlier in the season and had a good feel for the Gamecocks.
"Their defensive scheme I fit perfectly," Marcus said. "And they were my first scholarship offer. They showed the most interest in me first."
Marcus is the 24th commitment for the Gamecocks and the second of the weekend.
