NASCAR rivals throw punches in astonishing post-race brawl as security intervene

Security intervention was needed at the Kansas Speedway NASCAR race on Sunday after a bust-up between Ross Chastain and Noah Gragson.

Denny Hamlin won the race to go up to fifth in the Cup Series standings, but events off the track overshadowed the race. The incident took place on pit road shortly after the event had finished.

Gragson was unhappy with Chastain, and was visibly angry as he approached the 30-year-old after the race. The pair then had a heated verbal exchange, before Chastain threw a punch at Gregson.
