The Tennessee Titans have been busy addressing needs on the first day of free agency.

The Titans not only hauled in the biggest free agent prize among guards with Andy Levitre, but they also have agreed to a deal with tight end Delanie Walker.

Walker had been the No. 2 tight end in San Francisco, but will have the chance to play a bigger role in Tennessee with the impending departure of Jared Cook as a free agent.
