Titans' QB situation for Jaguars game remains uncertain

NASHVILLE, Tenn. (AP) — The Tennessee Titans still don't know who will start at quarterback Sunday against the Jacksonville Jaguars.

Marcus Mariota was limited all week with an arm injury and is questionable for the second straight game. Blaine Gabbert started in place of Mariota in Tennessee's 20-17 victory over the Houston Texans .

Titans coach Mike Vrabel said a decision could come in the next 24 hours.

The Titans will have left tackle Taylor Lewan back Sunday now that he's been cleared from the league's concussion protocol. Lewan had missed the Houston game after sustaining a hit from Miami Dolphins linebacker Andre Branch in the season opener .

The Titans ruled out running back David Fluellen (hamstring) and tackle Dennis Kelly (illness). Linebacker Kamalei Correa missed practice Friday and is questionable with a back injury.
