"Oakland Raiders running back Justin Fargas could be out for an extended period of time, according to ESPN, which reported that his injured groin may sideline him for "a few weeks." Raiders rookie Darren McFadden, who rushed for 164 yards in his second NFL game last Sunday against Kansas City, woule presumably step in for Fargas. Still, McFadden is slowed by turf toe and his status for Sunday's game at Buffalo hasn't been determined."
