Down to two healthy quarterbacks, the Titans signed Dominique Davis on Tuesday.

The Falcons, who had signed Davis as an undrafted free agent, released the former Boston College and East Carolina player in June.

Charlie Whitehurst has a pinkie injury on his throwing hand, leaving the Titans with starter Jake Locker and rookie Zach Mettenberger. Whitehurst was injured on Aug. 15 against the Saints, leaving Locker and Mettenberger to take all the snaps against the Falcons last Saturday.

Locker isn't expected to play much, if at all, in the preseason finale on Thursday against the Vikings at LP Field (7 p.m., WKRN-2, 104.5-FM).

The 6-foot-3, 210-pound Davis entered the NFL in 2012. He spent two seasons (2012-13) with the Falcons as the third quarterback on the 53-man roster, and played in one game (at Tampa Bay) in 2013.

As a two-year starter at East Carolina, Davis threw for 7,192 yards and 62 touchdowns.
