Hoping to rebound from their divisional road loss to the Chargers, the Raiders went home for a Week 7 divisional duel with their nemesis, the Kansas City Chiefs.  In the first half, Oakland trailed as Chiefs kicker Dave Rayner got a 41-yard field goal in the first quarter and a 31-yard field goal in the second quarter.  In the third quarter, the Raiders got on the board with QB Daunte Culpepper completing a 21-yard TD pass to WR Ronald Curry for the only score of the period.  In the fourth quarter, Kansas City retook the lead with RB Larry Johnson getting a 1-yard TD run (with a failed 2-point conversion).  Oakland managed to respond with kicker Sebastian Janikowski getting a 37-yard field goal, along with trying to turn a late-game drive into some winning points.  Unfortunately, the game ended with an interception. With the loss, not only did the Raiders fall to 2-4, but it also marked their 17th-straight divisional loss, the most since 1970.
