Things got pretty heated in Vegas when Kyle Busch got knocked out of the race at the last minute in Vegas. This after a bump from Joey Logano, and that's when it turned into a UFC event in the pits.
Kyle Busch wasn't very happy he got bumped by Logano so he hustled over to his pit area and started throwing punches.
Logano claims it wasn't intentional but it looks like he won the fight too.
