Marcus Mariota's status is uncertain, but there's good news: He feels better.
Mariota's injury, which the Titans are calling a stinger, is improving, according to coach Mike Vrabel, who hoped his quarterback can complete some work Monday and during the week. He is considered day to day.
Mariota missed the entire second half of Saturday's win over the Washington Redskins due to the injury, which he sustained while being sacked by defensive tackle Jonathan Allen. He was listed as questionable, but never returned as Blaine Gabbert led the Titans to a 25-16 win.
Gabbert was adequate in the victory, completing 7 of 11 passes for 101 yards and the go-ahead touchdown on a well-timed play-action bootleg pass to tight end MyCole Pruitt. But in the larger scheme, the Titans are undoubtedly better with Mariota under center than Gabbert, no matter how admirable of an effort he provided in relief. With a huge showdown ahead on Sunday night against the Colts, this will be a topic worth monitoring all week.
Tennessee will definitely be without perhaps its most important defender, though. Defensive tackle Jurrell Casey (knee) was put on injured reserve Monday. Casey suffered the injury Saturday, needed to be helped off the field and did not return.
In corresponding moves, the Titans added a third quarterback to the roster as they added quarterback Austin Davis for the second time this season and promoted linebacker LaTroy Lewis from the practice squad.
