Arkansas announced today that RB Jonathan Williams will be out for an extended period of time with a left foot injury that will require surgery. Williams has rushed for more than 2,000 yards and while the Hogs didn't give a timetable, an "extended period of time" certainly sounds like it would carry beyond the Vols' scheduled Oct. 3 contest inside Neyland Stadium with the Hogs. The game will be each team's fifth contest of the season.
