Race recap
A late race crash by Jimmie Johnson, combined with the win by Stewart, put him into the Nextel Cup points lead.  As part of the victory celebration, Tony Stewart went to turn two, where a fan handed him a can of Coca-Cola. Then upon returning to the frontstretch, Tony Stewart climbed the fence, along with the rest of his teammates. Kasey Kahne and Jeremy Mayfield finished 2nd and 4th for Evernham Motorsports. If Bill Elliott had finished in the top 10, all Evernham drivers would have finished in the top 10 for the first time that season.
