Mettenberger fills the void left by Bruce Gradkowski, who was placed on injured reserve with a hamstring injury.
Once seen as a "poor man's Tom Brady," the former Titans quarterback was cut by the team following mini camps in May after Tennessee signed Matt Cassel to back up Marcus Mariota. In 2015, Mettenberger took over for the injured Mariota on two occasions, finishing with a 60.8 completion percentage, 935 passing yards, four touchdowns and seven interceptions. Over his two years in Nashville, Mettenberger failed to win a single game.
The question now is whether the once promising arm can stay there.
