Champion Boxer Deontay Wilder Downs Internet Troll ...
The guy who got his face bashed in is Charlie Zelenoff -- a wannabe fighter who's been trolling Wilder for years with harassing phone calls and deeply personal jabs on social media.
Wilder claims Charlie has not only hurled racial slurs at him -- but also made disparaging comments about his young daughter, who was diagnosed with spina bifida.
Zelenoff had recently challenged Wilder to fight him at a boxing gym in L.A. -- and Wilder, deciding enough was enough, met him at the Hollywood Boxing Gym late Wednesday night.
