Pure chaos unfolded at BKFC 62 in Hollywood, Fla., on Friday night when a confused boxer attacked a referee after losing a fight by standing knockout. Bare-knuckle boxer Keith Richardson was left dazed on his feet following a powerful flurry from Alberto Blas, and it soon became obvious that Richardson was so rocked he’d completely lost sense of the situation. In a post-fight frenzy, Richardson started to throw punches at referee Sam Burgos, furiously charging at the retreating official.
