He is one of three Lions listed as such, joining cornerback Chris Houston (hamstring) and safety Glover Quin (ankle). Johnson, Quin, Houston, defensive end Ziggy Ansah and linebacker Ashlee Palmer were limited in practice.
It would be surprising if Johnson or Quin did not play against Green Bay. Houston is still dealing with the hamstring but said it is "coming along." He'll probably test it before Sunday's game to make sure everything is working well.
