It was recently revealed that heavyweight Dereck Chisora had been attacked by his own coach, Don Charles, during a training session. Preparations continue for his grudge match with David Haye on July 14. Chisora and Haye are due to fight it out at Upton Park after they became involved in a brawl at a press conference in Munich back in February. Charles said he had lashed out at Chisora after his charge had asked him to remove his headgear.

"I won't go into the details as to why he wanted his head gear off," he told BoxNation. "There's a way to tell someone something and it's called respect. I'm not a nutter. He asked me to take his head gear off and I physically attacked him. It's the worst thing that's happened since I've been with him and I've been with him for 10 years; I'm like a father to him.

"There is no father around, he's the man in his house so he finds it very hard to take instructions from another man. There is definitely a problem there. I regret attacking him because you should never put your hands on someone but I'm a human being with emotions so don't disrespect me. I will not tolerate it. My mother and father don't talk to me like that and certainly not someone I've helped for 10 years to become the boxer he is.
