CHARLOTTE, N.C. -- Shon Carson ran for 75 yards and a touchdown, linebacker Skai Moore intercepted two passes in the end zone and South Carolina defeated border state rival North Carolina 17-13 on Thursday night.

Carson, the Gamecocks' third-string running back, made an immediate impact on his first carry early in the fourth quarter, breaking free around right tackle and racing 48 yards for the go-ahead touchdown.

The Gamecocks intercepted Tar Heels quarterback Marquise Williams three times. Moore helped seal the game when he stepped in front of Williams' pass on a fourth-and-goal at the South Carolina 8 with 3:40 remaining.
