Pittsburgh, PA ( - The Pittsburgh Steelers placed defensive end Brett Keisel on injured reserve Monday.

The 13-year veteran played in all 12 games with the Steelers this season, starting four of them. He totaled 17 tackles and a sack.

To take his spot on the roster, the team signed defensive end Clifton Geathers, who has played 37 games since entering the NFL in 2010.
