Green Bay, WI (My Sportsbook) - Detroit Lions quarterback Matthew Stafford and wide receiver Calvin Johnson are both inactive for Sunday's contest at Green Bay.

Stafford and Johnson both missed practice Friday and were originally listed as questionable for the NFC North clash.

Stafford took limited snaps during Wednesday's practice, but did not participate on Thursday as he is still battling a right knee injury. He is listed as the emergency third quarterback.

Stafford was forced to sit out last Sunday's loss to Pittsburgh because of the injury sustained in a Week 4 defeat against Chicago.

Daunte Culpepper started in place of Stafford versus the Steelers and went 23- for-37 with 282 yards, one touchdown and one interception. He added 44 yards on the ground on three carries and was sacked seven times. He will get the start once again for Detroit at Lambeau Field.

Johnson limped off the field in the first quarter last week and was attended to by members of the training staff on the sidelines in the second half. He had just one catch for two yards in the game, and has 22 catches for 325 yards and a score this season.
