Per the report, the Titans will evaluate Mariota later this week, but the injury figures to make it tough for him to play Sunday against Atlanta.
Ken Whisenhunt relayed Monday that Mariota is "walking around fine," but did acknowledge with regard to his Week 7 status that the team isn't "going to do anything to put (Mariota) into any kind of jeopardy."
