Who is running for St. Louis: Starting running back Steven Jackson has not played a full season since his breakout year in 2006, meaning the team needs to find a dependable backup. None of the candidates impressed against the Falcons last week. Kenneth Darby is listed as the backup on the team's depth chart, and rushed for 30 yards on seven attempts last week.

Ochocinco kicks extra points and kickoffs, too. WR Chris Henry drew praise of QB Carson Palmer -- who will miss the game -- and the enigmatic receiver has scored a touchdown in each of the team's preseason games.
