Tennessee Titans quarterback Marcus Mariota is not expected to play against the Indianapolis Colts on Sunday night.
According to ESPN's Chris Mortensen, Mariota is dealing with a nerve condition caused by a stinger. While he will reportedly test his arm before the game, he has been told that further nerve damage could impact his ability to throw the ball long term.
NFL Network's Ian Rapoport confirmed that Mariota is not expected to play and that Blaine Gabbert would start.
Sunday night's game is a huge one since the winner will make the playoffs and the loser will be left out.
