Palmer's 2 TDs help Raiders down Vikings

Carson Palmer threw for a touchdown and ran 21, at the Metrodome.

Palmer passed for 164 yards and Michael Bush ran for 109 with a touchdown for the AFC West-leading Raiders (6-4), who have won their last two games. They also intercepted Minnesota quarterback Christian Ponder three times, including once in the end zone.

Ponder threw for 211 yards and two scores for the Vikings (2-8), who dropped their second consecutive game and lost running back Adrian Peterson to an ankle injury in the first quarter.

Oakland wide receiver Darrius Heyward-Bey left the game on a stretcher during the fourth quarter, after receiving a hit to his head.
