SMITTY: This is a complete bummer, as the guy had high-end RB written all over him heading into Week 13. It looks like he failed his final concussion test. It was a huge shot to the head that he took. We will keep you posted for next week, though. As for Week 13, it will be a total RBBC between Darren McFadden, Marcel Reece, and Maurice Jones-Drew. Looking for Week 13 Power Rankings?
