Things got pretty tense during a televised face-off between WBC heavyweight champion Vitalk Klitschko (43-2, 40 KOs) and his British challenger Dereck Chisora (15-2, 9 KOs). During the face-off, hosted by John Rawling and televised on BoxNation, the temper of Chisora flared up when Klitschko made a crack about his weight. Chisora has struggled with his weight in several fights. He was very overweight for his first career loss against Tyson Fury last July.

In response, Chisora alleged that Vitali was using steroids - a rumor that has circlulated about the Klitschko brothers for years, but nothing has ever been proven and nobody is exactly sure where the rumor started. During the second round of negotiations for Wladimir Klitschko vs. Alexander Povetkin, there was a major issue when Povetkin's camp demanded Olympic style drug testing to be involved. Initially, Vitali's younger brother refused to accept Povetkin's demand for the testing procedure, but he eventually agreed.

"At the press conference, you told me that you are already making the preparations. Are you already in shape? You have to burn 25-pounds of fat," Vitali said.

Chisora replied - "It don't matter. You don't worry about this fat man. I don't juice myself like you do, baby. This fat will be all over you, all over your face. You don't worry about me, you worry about yourself. What I'm doing is coming to this playground and I'm going to stop this big bully from taking people's candy from the playground - and you're the big bully."
