Marcus Mariota's availability for Sunday remains uncertain.

The Titans quarterback will be a game-time decision for the team's Week 5 game against the Dolphins, coach Mike Mularkey announced Friday.

"He did good for what we asked him to do," Mularkey said Friday, via the team's website. "We are not putting him through a point where we would make the (hamstring) any worse, so I think it feels good right now."

Mariota is listed as questionable on the team's injury report and considered day-to-day with a hamstring strain after leaving Sunday's loss to the Texans after halftime with the injury. Although he stressed his "first and foremost goal is just to get healthy," Mariota said he would "love to play" if he's 100 percent.
