Steelers release DE Brett Keisel

The Beard may be forced to move onto his life's work.

The Steelers announced the release of veteran defensive end Brett Keisel, just one year into the two-year deal he signed in August to return to the only club he's played for in 13 NFL seasons.

Keisel suffered a biceps injury late in the 2014 season, and was questionable to return with the team in 2015.

The release saves the Steelers $1.75 million on their 2015 salary cap, a figure that was getting tight after the signings of outside linebacker Arthur Moats and tight end Matt Spaeth earlier Monday.

Teams can officially sign pending free agents of other teams at 4 p.m. Tuesday, but those released can sign anywhere at any time. Keisel was reportedly heading to Arizona in August to talk contract with the Cardinals before deciding to sign with the Steelers after the preseason.

The move also suggests the team decided to keep Cam Thomas, a 2014 free agent signee who was less than impressive in his first year in Pittsburgh. It seemed like the team would decided between Thomas and Keisel, with one being released.

Second round draft pick Stephon Tuitt took over for Keisel, and looks to be the starter opposite Cameron Heyward heading into the offseason program.
