Detroit Lions quarterback Matthew Stafford and receiver Calvin Johnson both missed practice again on Friday.
Neither player was on the practice field during the 35-minute period the media is allowed to watch the workout.
Stafford, who practiced on Wednesday, did not practice on Thursday and it's highly unlikley he'll be available for Sunday's game against the Packers. Stafford has already missed one game with a right knee injury.
Johnson suffered a right knee injury in the first quarter last week against the Steelers and has not practiced all week. Both players are expected to be classified as doubtful, but the Lions don't have to make their injury report official until 4 p.m. today.
