Edwards saw Busch lead 415 consecutive laps Saturday night at Bristol Motor Speedway, then used him bumper to nudge Busch in the first turn on lap 470. That move caused Busch's car to wiggle just enough so that Edwards could drive by on his way to his second consecutive victory.
The triumph was also the sixth of the season for the Roush Fenway Racing driver, allowing him to close the gap of bonus points he's likely to face when the 12-race Chase for the championship begins. Busch has eight wins, and each is worth 10 Chase bonus points.
After taking the checkered flag, Edwards was making his cool down lap around the track when Busch drove up and bumped his car. Edwards clearly wasn't amused, and when he responded by driving the nose of his car into the right side of Busch's, the fans cheered wildly.
Busch finished second, followed by Joe Gibbs Racing teammate Denny Hamlin, Kevin Harvick and Jeff Gordon, three drivers needing good nights to bolster their playoff prospects.
Ryan Newman was sixth and was the only car not in Chase contention in the top 10. Clint Bowyer was seventh, followed by Clint Bowyer, Tony Stewart, Matt Kenseth and David Ragan.
