As many expected, Darren McFadden is unlikely to play for the Oakland Raiders this weekend against the Kansas City Chiefs. McFadden suffered a foot injury against the Chiefs earlier in the season and hasn't played since.
So that means we'll be seeing Michael Bush, who actually has had a lot of success against the Chiefs as a backup. Going by Bush's career numbers, he's good for one good game a year against the Chiefs.
His career against the Chiefs:
2008: 16 carries-90 yards
2009: 9 carries-35 yards, 14 carries-119 yards
2010: 5 carries-17 yards, 25 carries-137 yards
2011: 17 carries-99 yards
So perhaps he's already used up his one-good-game-against-KC and Saturday's numbers are more along the lines of 7 or 8 carries for 40 yards or so.
