Titans C Eugene Amano has been diagnosed with a torn triceps, and is done for the season.
Amano has been the Titans' starting center since 2008, but the team opened his job to competition following a dismal 2011, where he graded out as Pro Football Focus' fourth worst center. Fernando Velasco, Kevin Matthews and UDFA William Vlachos will now compete for the job, with Velasco as the favorite. The Titans may still explore a dried-up free agent market. Due a salary of $3.685 million in 2013, Amano has likely played his last snap with Tennessee.
