** FILE ** In this Nov. 10, 2008, file photo, Arizona Cardinals running back Tim Hightower (34) picks up yards as San Francisco 49ers' Walt Harris grabs his jersey during an NFL football game in Glendale, Ariz. Hightower started out as a fifth-round draft pick trying to crack the Arizona Cardinals' roster. Then he replaced Edgerrin James as the starting running back before fading down the stretch. After losing his job to James in the playoffs, Hightower came up with three of the biggest plays in Arizona's NFC championship victory over Philadelphia, which put the once-woeful Cardinals in the Super Bowl for the first time.
