Dereck Chisora brawled with British rival David Haye tonight in a confrontation which left the former WBA heavyweight champion's trainer and manager with a nasty facial cut.
After losing a brave 12-round decision to WBC champion Vitali Klitschko in Munich tonight, Chisora mocked the onlooking Haye for his poor performance against Klitschko's brother Wladimir last year - a fight which cost him his title.
Chisora then confronted Haye during the press conference and the two men grappled around the room with onlookers and entourages getting involved.
Someone - possibly Chisora - claimed to have been 'glassed' before grabbing a bottle himself.
Haye's trainer and manager Booth, who like Haye had been commentating on the fight, then appeared with a cut forehead, while someone held aloft a camera tripod threateningly.
Even by boxing's often chaotic standards the unsavoury incident was shocking, drawing gasps and cries of alarm as those involved fell about the room.
Klitschko - and brother Wladimir - seemed to stay out of it, before both Booth and Haye criticized the Ukrainians' manager Bernd Boente for not agreeing a fight between the Englishman and the WBC champion.
Haye, who had been working as a television pundit, was first to leave the scene, shouting abuse at Chisora, while Chisora urged Booth to check who injured him and insisted he was not at fault.
After Haye and Chisora were separated, Haye became involved in a fight with member of Chisora's entourage in which both men threw punches.
Haye then grabbed the camera tripod and swung it at the head of the character he was fighting with. Booth seemed to get caught in the middle and seemingly suffered the cut at the hands of his own friend.
Chisora and his promoter Frank Warren appeared to be trying to goad Haye into a high-profile fight between the two Londoners.
"David, how's your toe?" Chisora repeatedly shouted at Haye, referring to the injury he blamed his loss to Wladimir Klitschko on.
Haye said something back, to which Chisora said: "Do you want to tell me to my face? Tell me to my face!"
Chisora then left the stage, approached Haye and went nose-to-nose before appearing to push the former champion and initiate the brawl.
