Peterson, Minnesota's superstar running back, left the game with an ankle injury after gaining 26 yards on six carries. His absence meant that comeback duties fell to Christian Ponder after the Raiders opened a lead that stretched to 27-7 lead in the third quarter.
Ponder threw for 211 yards and two touchdowns, and ran for another 71 yards, but couldn't bring Minnesota all the way back, thanks in part to three interceptions.
The win pushes Oakland to 6-4 on the season. Minnesota falls to 2-8 with the loss.
