Tennessee Titans quarterback Marcus Mariota suffered an apparent injury to his hand or arm during Sunday’s game against the Indianapolis Colts.
Mariota went down just before halftime and appeared to be flexing his hand as he was treated by trainers. He left the game and went directly to the locker room.

Mariota dealt with a nerve issue in his elbow earlier in the season that caused him trouble gripping the football. It’s far too soon to know if this is somehow related to that or something new entirely. He had really raised his game over the past three weeks, with three consecutive 200-yard passing performances and five touchdowns over that span.
