nigger it's boxing, this is part of the sport. broken ribs, broken noses, knocked out teeth (maybe not so much nowadays with mouth guards everywhere), split lips, concussions, brain damage, occasionally broken facial bones or even skull fractures, that's what you sign up for when you get in the ring.
you can blame his opponent for not taking it seriously and not preparing to fight properly, you can maybe blame the jomhas for giving their fighters false expectations with their gay wholesome big chungus fun time charity event PR shit, but you can't blame the guy for playing to win. he fought according to the rules of the sport, he won fair and square.
