Frank Warren angered by talk of possible crowd trouble at David Haye-Dereck Chisora grudge match at Upton Park A Metropolian Police spokesperson told The Daily Telegraph on Thursday night: "We are aware of the event, and have been liaising with the organisers, the venue and London Borough of Newham, and an appropriate policing plan in place." Haye will concede 2½ stones to Dereck Chisora when the British rivals meet at the east London venue on Saturday night, after the protagonists weighed in at the Odeon Cinema, Leicester Square on Thursday, a venue once favoured for many big London fights by promoter Jack Solomons. Haye weighed 211lbs, the lightest he has been in his six heavyweight outings, with Chisora, the underdog, scaling 247lbs. As has become customary at the three public meetings of the two men, a 7ft high steel fence separated them. They weighed in on separate scales. They came face to face through the mesh, with Haye and Chisora exchanging words before Chisora's trainer Don Charles became animated and taunted Haye. Keep talking, keep talking. You're in trouble boy. Charles, who also brawled with Haye in Munich, later said: "I can't stand David Haye. The arrogance he shows is beyond belief. He's delusional and lives in a dream world. He's a guy who plays a lot of PlayStation games and he gets caught up in that mindset, he thinks it's all a game, but this is real. Chisora added: "We drive the same cars and we're going to have the same records. I've had three losses and after the fight he'll have had three losses. We'll be even. I'm coming for you. Haye then highlighted Chisora's lengthy criminal record and conduct within boxing as the reason for his hatred of the 28 year-old. Chisora's not a nice guy, and I don't like him for the fact he bites people in the ring, spits water in peoples' faces, slaps people at weigh-ins, kisses people at weigh-ins. What's to like?" he said. I don't know how anyone in their right man could support Dereck Chisora, a convicted woman beater. Who would support someone like that? Someone who says and does the things he does? What is there to support? What type of sane human being supports someone like that? Maybe another idiot would, someone like himself. Haye believes Puerto Rican referee Luis Pabon, sanctioned by the World Boxing Organisation and known as a disciplinarian, will deal with any erratic behaviour from Chisora. "We've got a good referee who won't stand for any foolishness and I'm confident he will handle anything," he said. Pabon told The Daily Telegraph that he would not have any qualms about disqualifying either man "if they failed to uphold the rules of boxing comportment inside the ring during the fight. Whatever happened before between them, it must be a sport in the ring on Saturday night. Hopefully they will wipe the slate clean and leave all their differences in the ring.
