BUSCH: Earnhardt Jr takes controversial win.

Dale Earnhardt Jr had to endure something that he rarely has to put up with after Saturday's Carfax 250 Busch Series race as he claimed a very un-popular victory with the Michigan crowd.

Earnhardt Jr bumped Carl Edwards into a spin during a green-white-chequered flag finish to take the win and was given the kind of fan reaction usually reserved for Kyle Busch when he pulled into victory lane.

Earnhardt Jr would be classed as the winner by NASCAR but Edwards, who dropped to 23rd as a result of the spin, could find himself in hot water after ramming the side of Earnhardt Jr's machine behind the pace car.

In the confusion Casey Mears moved in to second place with Robby Gordon third, Matt Kenseth fourth and Mark Martin fifth.

Championship leader Kevin Harvick finished eighth as Nextel Cup drivers claimed 16 of the top 17 positions.
