\ Today, the Redskins released Mathis, a receiver who was with the Houston Texans before legal and injury troubles derailed his career.\
\ The signing of Mathis — a return specialist — never made sense considering the Redskins re-signed Rock Cartwright during free agency.\
\ In Mathis’ place, the Redskins signed defensive end J.T. Mapu.\
\ Mapu (6-4, 290) played at Tennessee, posting 65 tackles. He tried out during the Redskins’ mini-camp earlier this month.
