Dolphins quarterback Tua Tagovailoa was carted to the locker room in the first quarter of Miami's matchup with the Bills on Sunday.
Tagovailoa exited the contest after he was hit on a 4th-and-2 play by Buffalo defensive lineman A.J. Epenesa. Tagovailoa threw an incomplete pass before he was hit, and he attempted to walk to the sideline before trainers came to look at him.
The second-year quarterback was helped to the sideline by team trainers, but he was taken into the locker room by a cart. He was later ruled questionable to return with a rib injury.
