Boxer Dereck “Del Boy!” Chisora from Zimbabwe is one cheeky laaitie. After giving Vitali Klitschko a PK during their weigh-in before Saturday’s WBC heavyweight championship fight, he also spat in Klitschko’s brother’s face. After losing said fight, Chisora then got into another bloody brawl with rival UK fighter David Haye the next morning at a press conference. Footage of all incidents after the jump.
