Raiders' running back Justin Fargas could miss a few weeks of action because of an injured groin, according to Contra Costa Times.
Without Fargas, Oakland would likely give a majority of the carries to rookie Darren McFadden, who happens to be suffering from turf toe and isn't a lock to play Sunday.
Michael Bush will start if both Fargas and McFadden aren't able to play.
