Rams running back Marshall Faulk will return to practice this week and he may find himself back in a game on Sunday. It was learned yesterday that Lamar Gordon’s ankle sprain is worse than expected, which could leave them perilously low at running back as they head to Pittsburgh. Arlen Harris filled in for Gordon on Sunday, rushing for 85 yards and a touchdown. He’s now listed as questionable for Sunday with a high ankle sprain. Faulk went down in week three with broken bones in his hand. He also decided to have a procedure to clean out his knee. If Faulk doesn’t play, the Rams will enter Sunday’s game against the Steelers with Harris and Joffrey Reynolds, who are both un-drafted rookies.
