Fooch's update: Culliver has been ruled out for remainder of Raiders game.
San Francisco 49ers cornerback Chris Culliver suffered a left knee injury against the Oakland Raiders, and is questionable to return. He suffered the injury early in the second quarter on a goal line run by the Raiders. He was able to walk off the field under his own power, but he took a cart to the locker room shortly after. The injury is to the same knee in which he suffered a torn ACL. He has yet to return to the game as of publishing.
The 49ers cornerback depth is fairly limited. Dontae Johnson moves from nickel back to outside cornerback, opposite Perrish Cox. Leon McFadden takes over nickel back duties, and at this point he is the only remaining cornerback. The remaining defensive backs on the bench include Craig Dahl and L.J. McCray, both of whom are safeties. McFadden has only played two snaps this season, but could find himself getting a decent amount of work this week.
