Chisora slaps Klitschko at weigh-in, champion saves response for Saturday night

For the first time in his 15-plus year professional career, boxing champion Vitaly Klitschko was slapped in the face by challenger Dereck Chisora at the weigh-in for their heavily anticipated heavyweight bout in Munich on Saturday.

While the two were posing for photographs, the Zimbabwean-born Briton smacked Klitschko hard with his open right hand. With his face partially concealed by a Union Jack bandana, the challenger also launched a series of insults at the champion.

Later, it was revealed that the World Boxing Council issued Chisora a $ 50,000 fine for his stunt.

The Ukrainian WBC holder, unfazed by his opponent's antics, did not hit back. But on Saturday night, 12,500 spectators will witness Klitschko's response to that slap in Munich's Olympic Hall.

Twenty-eight-year-old Chisora has promised to knock out the elder Klitschko brother despite being a massive underdog for the fight. He also weighed in at almost a kilogram lighter than 40-year-old Vitaly.

The elder Klitschko is the second-oldest boxer to hold a world heavyweight title behind George Foreman, who was 45 when he knocked out Michael Moorer to reclaim the WBA belt in Las Vegas in 1994.
