Mariota is listed as questionable for the game after being limited in practice Friday because of neck and foot injuries. Vrabel said the quarterback hasn't made much day-over-day progress in his return from injury.
"About the same as it was yesterday," the Titans head coach said, per the team's official website. "(He was) limited, and we gave him some stuff to do, and he did some stuff. So we'll kind of just keep seeing where it goes, and figure out who gives us the best chance, and how he feels. We want to make sure he can go out there and do his job at a high level."
Mariota missed practice Wednesday and was limited on Thursday and Friday after suffering a stinger during Saturday's win over the Washington Redskins. He told reporters earlier this week he is confident he could perform well in the game even if he missed practice time.
