Darren McFadden missed a third straight day of practice because of a hamstring injury, making it all but certain the Oakland Raiders will be without their top running back for Sunday night's game against San Diego.

McFadden has been sidelined since getting hurt early in the first half of Oakland's 24-14 loss to the Washington Redskins on Sept. 29. He is listed as questionable on the team's injury report.

Raiders coach Dennis Allen said Friday that McFadden's status would be a game-time decision but noted he had made progress and was getting closer to returning. McFadden, however, sounded less optimistic when speaking to reporters, saying he still feels pain just from walking.

McFadden has missed at least three games in each of his five previous seasons in the NFL.
