Williams (shoulder) is listed as doubtful for Sunday's game in Detroit, Tom Silverstein of the Milwaukee Journal Sentinel reports.
Coach Matt LaFleur essentially confirmed earlier Friday that Williams won't play, leaving Dexter Williams and Tyler Ervin as the reserve options in Green Bay's backfield. The situation could lead to extra touches for Aaron Jones, as it isn't clear if the team will trust Williams or Ervin to handle significant work in an important game. A victory would give the Packers a shot at the NFC's No. 1 seed, while a loss could drop them as low as No. 3. A first-round bye in the postseason would help Williams avoid any additional missed time beyond Sunday.
