Report: Titans considering Zach Mettenberger at quarterback

With Jake Locker's constant struggle to stay healthy and Charlie Whitehurst's ineffective play, the Tennessee Titans could be looking at a different option to start at quarterback. 

The Titans drafted Mettenberger in the sixth round - despite the fact he tore his ACL at LSU last season - with the hope he could be groomed to be a future starter. 

The Titans would probably prefer not to rush him onto the field, but given their continued struggles, and Locker's injuries, they may not have a choice.
