(AP) - Down to one healthy running back, the Pittsburgh Steelers have brought back two players from last season by re-signing Najah Davenport and promoting Gary Russell from the practice squad.

The Steelers, third in the NFL in rushing last season, lost Pro Bowl running back Willie Parker to a sprained knee last week. He will not return until Oct. 19 at Cincinnati at the earliest.

The team also lost first-round draft pick Rashard Mendenhall to a season-ending fractured shoulder Monday night against Baltimore.

Mewelde Moore, normally the Steelers' third-down back, is expected to start Sunday night in Jacksonville. He was limited to one carry this season before the 23-20 overtime win over Baltimore. Moore has started 11 games in his career, rushing for 100 yards or more in four _ two with the Vikings in 2004 and two more in 2006.

Davenport, a former Green Bay Packers player, was the Steelers' second-leading rusher last season with 499 yards and a 4.7 yards per carry average. He also led them with five rushing touchdowns and had two more touchdowns as a receiver.

Russell made the Steelers' 53-man roster as an undrafted free agent last season but was taken off the roster to clear room for a special teams player.
