Mariota did not return to Sunday's game against the Patriots after exiting the contest in the second quarter with a right knee injury.

Analysis:

The status of Mariota, who missed two games earlier this season after injuring his left knee, is thus worth tracking leading up to Week 16's contest against the Texans. If Mariota is unable to play next weekend, Zach Mettenberger would be in line to helm the Titans' offense.
