Dereck Chisora has slapped Vitali Klitschko at the weigh-in ahead of the WBC heavyweight title challenge in Munich.
The eccentric Londoner is a rank outsider ahead of the weekend's bout and attempted to get under the long-reigning champion's skin.
After weighing in at 17 stone 3lbs - just a pound heavier than his lightest weight for a professional bout - Chisora butted heads before slapping Klitschko's face hard.
The two men were pulled apart, with a furious-looking Klitschko, who had weighed in three pounds heavier, left with a red mark on the left side of his face.
Chisora's camp said they were unaware of the stunt beforehand, with trainer Don Charles even branding the slap "unacceptable".
