Coach Mike Vrabel said Mariota (elbow) will be re-evaluated Wednesday, Travis Haney of The Athleticreports.
The Titans have taken a cautious approach with Mariota, and Vrabel reiterated earlier in the week that the young quarterback wouldn't be rushed back onto the field. Wednesday's update should provide a clue as to Mariota's availability in Week 3, though even if he can return to the field, he will draw a tough matchup at Jacksonville.
