Former Packers running back Najeh Davenport signed with the Steelers on Friday. Davenport, who has rushed for 1,068 yards in 39 NFL games, missed most of last season after breaking an ankle Oct. 9 against New Orleans. The 6-foot-1, 247-pounder was released last weekend by Green Bay. Davenport is expected to give the Steelers a power running back in the mold of the retired Jerome Bettis.
