The Tennessee Titans, having just released Matt Hasselbeck, have some serious interest in former Buffalo Bills starter Ryan Fitzpatrick, per a source with knowledge of the situation.

Fitzpatrick was the Bills' starter for the past three seasons before being released just over a season after signing a deal with the Buffalo Bills in 2011 with $24 million in guaranteed money. He was let go at the start of free agency by the Bills and has had overtures from the Bengals and Titans of late.

The Titans are looking for a quality veteran backup to play behind Jake Locker, who is still recovering from off-season shoulder surgery.
