Arkansas RB Rawleigh Williams out indefinitely after neck surgery

Arkansas running back Rawleigh Williams underwent neck surgery Saturday evening after he was carted off the field with a neck injury against Auburn.

The freshman running back tweeted Sunday that he's expected to make a full recovery.

Arkansas released a statement Sunday afternoon and said the timetable for Williams' return is unclear.

Williams was injured when he was tackled on a third quarter carry. He was grabbed by the facemask as he was tackled by multiple Auburn players and his neck was jerked back. Arkansas eventually beat Auburn 54-46 in four overtimes.
