Trying to snap a six-game losing skid, the Raiders flew to Arrowhead Stadium for a Week 12 AFC West rematch with the Kansas City Chiefs. In the first quarter, Oakland took the early lead as kicker Sebastian Janikowski managed to get a 25-yard field goal. However, the Chiefs took the lead with RB Kolby Smith getting a 10-yard TD run. In the second quarter, the Raiders drew closer as Janikowski kicked a 54-yard field goal. However, Kansas City managed to get one last strike prior to halftime as kicker Dave Rayner nailed a 30-yard field goal. In the third quarter, Oakland regained the lead with RB LaMont Jordan getting a 5-yard TD run.  However, the Chiefs retook the lead with Smith getting a 5-yard TD run.  In the fourth quarter, the Raiders once again jumped into the lead as RB Justin Fargas got a 14-yard TD run.  This time, the defense managed to hold on for the win. With the win, not only did the Raiders improve to 3-8, but they managed to do four things with their one win. First, they snapped their six-game losing skid. Second, they snapped a nine-game losing skid to the Chiefs. Third, they snapped a 17-game losing streak against divisional opponents with their first divisional win since 2004. And finally, they surpassed their regular season win total from last season.
