Cornerback Josh Wilson is questionable.
Levy has a hip injury. Pettigrew has injuries to a knee and elbow. Neither practiced Wednesday through Friday. Wilson's injury is listed as a concussion and he remains in the NFL's protocol program. He had a limited practice Friday.
Detroit also released defensive tackle Ishmaa'ily Kitchen.
Both the Vikings (3-2) and Detroit (1-5) are trying to win a second straight game in the NFC North.
