There's already concern in this area, as running back Darren McFadden has a midfoot sprain of unknown severity. He could be back against Denver on Nov. 6, but it's no slam dunk.
The Raiders can get by without RB Darren McFadden for short periods of time by using Michael Bush and increasing the workload of explosive rookie Taiwan Jones.
If McFadden were to be out for an extended amount of time because of this injury or one down the road, the Raiders aren't deep enough to be a championship level team without their most dynamic playmaker.
