Receiver Calvin Johnson is questionable for the Detroit Lions for Sunday's game at Green Bay because of an ankle injury.
Johnson didn't practice Friday after being limited earlier in the week.
Detroit ruled out cornerback Rashean Mathis (concussion) and listed safety Isa Abdul-Quddus (foot) as questionable.
The Lions are coming off an open date. The 30-year-old Johnson has not missed a game this season. He has 48 catches for 659 yards and three touchdowns.
