ALAMEDA, Calif. — After spending most of the first two months of the season as Darren McFadden's backup in Oakland, Michael Bush seemed to have little chance to reach the 1,000-yard milestone coveted by NFL running backs.

With McFadden slated to miss his eighth straight game with a sprained right foot, Bush is getting into range of that target. He has 841 yards rushing this season for the Raiders (7-7) with two games remaining, starting with Saturday's visit to Kansas City.

Bush has had some of his best performances against the Chiefs during his four seasons in the NFL, including a 137-yard performance in the season finale at Kansas City a year ago that helped the Raiders avoid an eighth straight losing season.
