The Steelers today made a roster move, adding third-year defensive end Kevin Huntley off waivers from the Washington Redskins.  Huntley (6-7, 290) originally signed with the Oakland Raiders as a rookie free agent from Kansas State in 2006. He played in the final five games of his rookie season with Oakland and registered 10 tackles, 2.5 sacks and a recovered fumble. He spent the 2007 season with the Atlanta Falcons and recorded three tackles while playing in five games.  The Steelers made room for Huntley on their roster by releasing rookie free agent defensive end Kyle Clement.
