ST. LOUIS (AP) -- Defensive end Chris Long was a full participant in St. Louis Rams practice, making it likely he'll return after missing four games with a knee injury.
Center Tim Barnes was limited with a concussion and the Rams held out defensive end Robert Quinn (hip) and rookie offensive tackle Rob Havenstein (calf).
Quinn is expected to get more playing time this week at Baltimore after getting 14 snaps last week.
Long fractured a bone in his right knee at Green Bay Oct. 11.
