FILE - Tennessee Titans tight end Delanie Walker (82) drags Houston Texans cornerback Kevin Johnson (30) into the end zone as Walker scores a touchdown during the second half of an NFL football game Dec. 3, 2017, in Nashville, Tenn. Walker, a three-time Pro Bowl tight end, finally retired Tuesday from the NFL after 14 seasons––nearly three years after his final game. A new job helped Walker realize that the time to transition had arrived. (AP Photo/James Kenney, File)
