Rams' running back Steven Jackson hopes to return this weekend against the Cardinals after missing a game because of a thigh injury. "I'm practicing to play, if that tells you anything," Jackson said Thursday. St. Louis Coach Jim Haslett believes Jackson has a 50-50 shot to play on Sunday. "I think he's going to be a game-time decision, but he worked a little bit today," Haslett said. "I know he feels a lot better."
