NFL Network analyst Ian Rapoport has stated that the Tennessee Titans are 'unsure' over the future of quarterback Jake Locker.

Locker suffered a season-ending Lisfranc injury during his side's loss to the Jacksonville Jaguars last weekend, though it is not the first time he's been on the treatment table recently.

With the Titans concerned that they can't rely on Locker for a full 16-game season, a decision must be made before the next NFL Draft whether to choose a quarterback or not.

Rapoport said via his Twitter account: "Titans undecided about how to proceed with Jake Locker, who they have felt, at times, is their franchise QB if he didn't have injury issues."

Ryan Fitzpatrick will lead the Titans when they take on the Indianapolis Colts on Thursday night.
