Mariota improving; Titans add QB Davis; Casey to IR

The Tennessee Titans are hopeful of having quarterback Marcus Mariota available to start in Sunday night's win-and-in regular season finale against the Indianapolis Colts.

That said, the Titans have hedged their bet on his health by re-signing veteran quarterback Austin Davis to serve as a third-stringer behind Mariota and Blaine Gabbert, who rallied the Titans past the Washington Redskins on Saturday to set up Sunday night's showdown. Davis was on the Titans roster earlier this season when Mariota missed the Titans' home opener.

Mariota suffered a stinger injury just before halftime against the Redskins, and did not return. He has been knocked out of games with similar injuries twice before this season. Titans coach Mike Vrabel said the injury is officially a stinger and not the elbow injury that numbed his throwing arm in the season opener at Miami. Mariota also left the Titans' first meeting with the Colts with a stinger injury.

“We'll see kind of where he's at today and do a little bit of individual work on the field, and see if he can do any of that stuff and keep moving on toward the end of the week and make sure he can do everything that we ask our quarterbacks to do,” Vrabel said.

As to Mariota's health, Vrabel said his quarterback is better now than he felt in the aftermath of the previous two injuries.

“He feels a lot better than what he did after both of those games, after talking to him this morning,” Vrabel said.

While the Titans are playing wait-and-see with Mariota, they will be without defensive tackle Jurrell Casey, who has been placed on injured reserve after suffering a knee injury against the Redskins on Saturday.

“I don't think we'll have Jurrell probably this week. It'll be tough. I think he'll do everything he can to rehab, but I don't think he'll be available this week,” Vrabel said before the announcement of Casey going on injured reserve was reported.
