After missing the Tennessee Titans' Week 5 defeat to the Miami Dolphins, Marcus Mariota will be back on the field Monday night against the Indianapolis Colts, Titans beat writer Paul Kuharsky reported Sunday. The Titans listed Mariota as questionable with a hamstring injury on the Week 6 injury report. "It is going to come down to a lot of things," head coach Mike Mularkey said after Friday's practice, per Jim Wyatt of the team's official website. "It might be a game-time decision. Can he play and not risk himself further injury? That’s the biggest thing."
