Marcus Mariota injured his hamstring at the end of the first half against the Texans. The team has said he is questionable to return, but they aren’t bringing him back in this game. There is no reason to risk further injury in a game the Titans haven’t been in since the opening kickoff.
I really wish the Titans could figure out a way to be consistent. They aren’t going to be a team that is actually in contention until they figure that out.
