Trying to snap a three-game skid, the Chiefs went home for a Week 12 AFC West rematch with the Oakland Raiders.  In the first quarter, Kansas City trailed early as Raiders kicker Sebastian Janikowski managed to get a 25-yard field goal.  Afterwards, the Chiefs regained the lead as rookie RB Kolby Smith managed to get a 10-yard TD run.  In the second quarter, Oakland played catch-up as Janikowski kicked a 54-yard field goal.  Kansas City improved its lead before halftime as kicker Dave Rayner nailed a 30-yard field goal. In the third quarter, the Raiders regained the lead with RB LaMont Jordan getting a 5-yard TD run.  The Chiefs would respond with Smith getting a 5-yard TD run.  However, in the fourth quarter, Oakland regained the lead with RB Justin Fargas getting a 14-yard TD run.  Kansas City tried to come back, but the Raiders held on for the win. With their fourth-straight loss, not only did the Chiefs fall to 4-7, but it snapped their nine-game winning streak against the Raiders.  This would be the first time since 2004 that Kansas City had dropped four-straight games. Kolby Smith, in his first game starting in absence of Larry Johnson, had 31 carries for 150&#160;yards on the day.
