Four total turnovers increased the Chiefs league lead in that category to 25 as the Oakland Raiders won on the road for the first since a December 2011 victory at Arrowhead in a 26-16 final.
The Chiefs have yet to lead in a game this season, with their only win coming in overtime. The Chiefs managed to tie the game at 6-6 after Ryan Succop matched Sebastian Janikowski with field goals in the first half, but Carson Palmer threw the first of his two touchdowns late in the half to give the Raiders a lead that was never in jeopardy.
Brady Quinn got picked off once and was 2 for 4, before leaving with what the team describes as a head injury. Matt Cassel was also picked off one and threw for 218 yards and a late touchdown pass to Dexter McCluster. It was the Chiefs first offensive touchdown since Sept 30 at San Diego.
