Darren McFadden has missed at least three games in each of his first three seasons, so Michael Bush knows this drill, now that it appears McFadden could miss Sunday's game against the Denver Broncos.
Bush, in his fourth season, has been the trusted backup who has filled in with solid games.
The last time Bush ran 20-plus times was in the 2010 season finale at Kansas City, when he gained 137 yards on 25 carries with a touchdown. He has topped 100 yards in three of the five games in which he has had 20 or more carries.
In his 10 career starts, in which the Raiders are 4-6, Bush has run for 600 yards on 134 carries with four touchdowns.
The Broncos have given up the 8th-fewest Adjusted FP to RBs, so this isn't a great matchup, but Bush is still a fringe RB1 this week since the Raiders are so run-heavy. He should see a ton of work and is a good bet to find the endzone.
