Corey Davis likely to return vs. Ravens; Marcus Mariota back to 100 percent

NASHVILLE, Tenn. -- The return of Titans rookie receiver Corey Davis is imminent, and it's likely to come Sunday against the Baltimore Ravens.

Davis returned to practice Monday, on a limited basis, for the first time since Week 2, when he suffered a hamstring injury that caused him to miss five games.

"I'm feeling the best I've felt. I'm feeling real confident this week," said Davis, the No. 5 overall pick out of Western Michigan, noting he'll "definitely" be 100 percent if he's out there this week. "It's been tough on me, but the main thing is me staying positive."

Good injury news wasn't limited to Davis. Titans coach Mike Mularkey said quarterback Marcus Mariota is back to 100 percent and should be able to do everything Sunday against Baltimore. Mariota is finally past the hamstring injury that caused him to miss one game and left him primarily restricted to the pocket over his past two games.

"Marcus is back to where we need him to be to play at the same level he did before the injury," Mularkey said.

Davis initially suffered the hamstring injury a few days into training camp and missed the entire preseason. He returned in Week 1 and made a splash, catching six passes for 69 yards in his NFL debut. He reinjured the hamstring in Week 2.

Davis admitted he rushed himself back from the first hamstring injury, but said the team let it heal fully this time so it won't happen again.

Left guard Quinton Spain, who has the most serious of the Titans' injuries, is doubtful to play Sunday with a turf toe injury he aggravated against Cleveland. Brian Schwenke would start in his place.

Tight end Delanie Walker did not practice with a right ankle bone bruise, but Mularkey noted it was mostly due to the fact the Titans had an extra day of practice this week.

Safety Johnathan Cyprien returned to practice on a limited basis for the first time since suffering a hamstring injury in Week 1. Mularkey said Cyprien's practice reps were plentiful, similar to Davis, leading to a decent chance he'll push to play Sunday as well.
