Shane Cottle and Brad Kuhn got into each other on the track during the last lap of the second B Main. When Cottle got out of his wrecked car, he was furious, and looking for Kuhn. He found him in the pit area, and things got kind of hairy after that.
Punches were thrown, nasty words were uttered, and, eventually, the two drivers were separated.
The best part of the fight, though? It appears that NASCAR drivers Kasey Kahne (wearing his Great Clips fire suit) and Kyle Larson were both on hand to take in the melee.
