South Carolina quarterback Connor Shaw sprained his knee in the fourth quarter Saturday while taking a sack and had to be helped off the field.
"How serious, they'll have to wait and evaluate," coach Steve Spurrier said after the game, according to Michael Haney of 107.5 The Game.
Shaw's left leg folded underneath his backside as he was tackled. The Gamecocks held a 21-20 lead at the time of the injury, with Shaw orchestrating a comeback. The quarterback completed just 7-of-21 for 161 yards, but scrambled 19 times for 78 yards and a touchdown.
Experienced backup Dylan Thompson completed his only pass attempt on the next play, a third-and-12, and South Carolina rushed three times before punting on its next and final possession. Tennessee drove 63 yards and kicked a short, game-winning field goal.
Shaw threw his first interception of the season Saturday and has 11 passing touchdowns. He's rushed for 397 yards and three touchdowns.
South Carolina (5-2, 3-2) travels to Missouri (7-0, 3-0) next week. The Tigers are playing without starting quarterback James Franklin (shoulder).
