Speeding cars escalated into swinging punches at Sunday night’s NASCAR All-Star Race in North Carolina, where drivers Ricky Stenhouse Jr. and Kyle Busch got into a fight that later involved their crews.

Tempers apparently flared after Busch bumped Stenhouse's No. 47 Chevrolet Camaro ZL1, causing the car to slam into a perimeter wall, according to NASCAR. The crash knocked Stenhouse out of the race after just two laps (out of 200) at North Wilkesboro Speedway.
