Rubbin' may be racin', but intentionally wrecking someone isn't and it can lead to massive brawls breaking out. That's exactly what happened near the end of yesterday's race in Arizona. Jeff Gordon was apparently frustrated with Clint Bowyer and with a few laps left, Gordon showed Bowyer what he thought of him.
Gordon's move obviously wasn't well appreciated by Bowyer's crew, leading to a massive fight in pit row. Bowyer was able to join the fracas once he made his way back to the row after getting out of his crashed car. Both Gordon and Bowyer met with NASCAR officials after the incident and Gordon told reporters afterwards that he wrecked Bowyer because he's been messing with him all year on the tracks.
