Quarterback Deshaun Watson has left No. 18 Clemson's game against No. 24 Georgia Tech with an apparent left knee injury.

Watson, who returned as a starter after missing three games with a broken bone in his right hand, was hurt when making a cut late in the first quarter of Saturday's game. Watson ran for 7 yards and a first down before falling to the ground and grabbing his left knee.

Watson, a freshman, walked off the field and was escorted to the locker room. Clemson did not have an immediate update on the severity of his injury.

Cole Stoudt replaced Watson and had a pass intercepted on his third play by Jamal Golden and returned 93 yards for a touchdown.
