The Titans still don’t know if they’ll have quarterback Marcus Mariota on the field Monday night against the Colts. Mariota, who missed last week’s game with a hamstring injury, has been listed as questionable this week. He was limited in practice during the week and Titans coach Mike Mularkey said it could come down to a game-time decision. If Mariota can’t go, Matt Cassel will get the start against the Colts.
