It came pretty close to a game-time decision, but Rams running back Steven Jackson will start when St. Louis hosts Arizona on Thursday Night Football.
Jackson has been hampered by a groin injury, and his participation wasn't a sure thing heading into the game. Wide receiver Danny Amendola missed some time this week but is active.
Inactive for St. Louis are defensive tackle Matt Conrath, safety Matt Daniels, running back Terrance Ganaway, offensive tackle Rodger Saffold, defensive end Eugene Sims, wide receiver Steve Smith and quarterback Austin Davis.
Cardinals defensive tackle Darnell Dockett will give it a shot Thursday after being limited in practice this week. Quarterback John Skelton was not as fortunate and will not participate in the game. Kevin Kolb will get the start for the Cardinals.
Kickoff is scheduled for 7:20 p.m. CT.
