Steelers add Davenport; waive Cobbs

Pittsburgh added an experienced running back to its roster today, signing veteran Najeh Davenport, 27, to a one-year contract. Davenport (6-1, 247), a five-year veteran, spent his first four NFL seasons with the Green Bay Packers. Davenport missed most of last season after breaking his ankle on Oct. 9, 2005 against the New Orleans Saints.

Pittsburgh made room on its roster for Davenport by releasing rookie RB Patrick Cobbs.
