Raiders signed RB Jamize Olawale off the Cowboys' practice squad. It's an interesting move with Darren McFadden and Mike Goodson due back this week and Jeremy Stewart and Marcel Reece playing well. Olawale is a converted wide receiver and fullback, so the Raiders may envision him as a lead blocker. He showed well in preseason action.
