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 (Wladimir Klitschko) face. The next day, Chisora lost the fight by points through unanimous decision and Klitschko retained his WBC title.

This happened during the same month Clarence Tillman III also provoked his boxing opponent, Sonny Bill Williams, during weigh-in – only to get knocked out during the first round of the fight.

See both the PK and the spitting incident below:

During a post-fight press conference, Chisora was involved in an ugly confrontation with another boxer, David Haye, who appeared during the conference to taunt Chisora over his loss and again challenged Klitschko to fight him in the ring.  The next morning, Chisora was arrested by German police for his part in the brawl.

Here’s Chisora’s “altercation” with Haye:
