Evidently Guy Whimper and D'Anthony Batiste were not the tackles the Pittsburgh Steelers were looking for. The Steelers have waived recent waiver claim Buddy Jackson a defensive back formerly of the Kansas City Chiefs and the University of Pittsburgh. They waived Jackson to re-sign offensive tackle Mike Farrell an undrafted rookie out of Penn State. Pittsburgh is still trying to figure out who will back up Marcus Gilbert and Mike Adams at the outside tackle positions. Kelvin Beachum is in the mix but has been working primarily inside. Farrell will rejoin Joe Long and Mike Golic Jr. to compete for roster and/or practice squad spots.
