Raiders RBs Darren McFadden and Mike Goodson BOTH have high ankle sprains.
Oakland will turn to some combination of Marcel Reece and Taiwan Jones as the dreaded high ankle sprain means McFadden and Goodson could miss significant time. However, McFadden hasn't officially been ruled out, according to the team.
Reece is a fullback and Jones a speed guy, so the two are likely to both see carries - depending on situation - if McFadden is out. Reese seems like the more usable pickup and was the Raiders leading receiver with 8 catches this week. The team has also said they don't trust Jones because of ball security issues. The Raiders will likely move to a more pass-heavy attack and split RB touches.
