Mettenberger did not play during Friday's preseason win over the Cardinals.
Despite default starting QB Philip Rivers resting on the sideline, Mettenberger saw veteran backup Kellen Clemens and undrafted rookie Mike Bercovici take the majority of the snaps throughout the contest on Friday. A starter for the Titans when now current Chargers offensive coordinator Ken Whisenhunt was the head coach, many assumed Mettenberger could earn the No. 2 spot if he performed well during the preseason. That doesn't appear to be in the cards, however, as he has been seemingly bypassed on the depth chart by both Clemens and Bercovici and could be in danger of being released.
