Tagovailoa walked off the field and was taken to the sideline medical tent during the second quarter Saturday night. The 2018 Heisman Trophy runner-up then was escorted to the locker room while Mac Jones took his place.
No. 1 Alabama's coach Nick Saban says Tagovailoa is likely to miss the Arkansas game with the injury. Tennessee quarterback Brian Maurer also was hurt in the first half, sustaining a concussion.
Tagovailoa called a timeout just before the play clock ran out after a sack and walked to the sideline.
He was 11 of 12 for 155 before the injury. Tagovailoa did throw an interception on first-and-goal from the 2 when he tried to force the ball while scrambling.
