MUNICH — Challenger Dereck Chisora slapped WBC heavyweight champion Vitali Klitschko during the weigh-in for their title fight on Saturday.
Both camps had to be pulled apart Friday after the British fighter slapped Klitschko with his right hand and launched a series of insults.
Chisora has been taunting Klitschko and predicting that he will knock him out in the eighth round.
