David Haye has released an iPhone app where users can play as him and slice off Dereck Chisora's head with a bottle.
The controversial game shows Haye taking the bottle out of his glove before using it to decapitate his fellow British heavyweight, who he will face at West Ham's football stadium on July 14th.
The bottle incident in the app makes fun of the pair's highly publicised brawl at a news conference in Munich following Chisora's defeat by WBC title holder Vitali Klitschko in February.
The Haye-Chisora fight is only going ahead after promoter Frank Warren managed to get it sanctioned by the Luxembourg Boxing Federation despite neither boxer holding a current licence with the British Boxing Board of Control.
Haye admitted that his iPhone game, which is being sold to anyone over the age of nine is likely to cause controversy.
"So much fuss was made about the bottle in my hand in Munich that I decided to have some fun with it," he is quoted as saying in The Sun.
"People will moan about it but I have a simple message - keep your money in your pocket and don’t buy it.”
It is the second time that Haye has released a contentious app just before a big fight. Before his bout with Wladimir Klitschko last summer he released a game that allowed users to literally knock the head off his opponent.
The iTunes store has rated Haye's game suitable for a 9+ audience, saying the rating is for "Frequent/Intense Cartoon or Fantasy Violence".
Haye ended up losing the fight to Klitschko by unanimous decision.
Haye also admitted that during the brawl in Munich he broke the jaw of Chisora's trainer.
"Chisora has an idiotic coach called Don Charles, who has offered me out in a fight after I’ve broken his jaw at the press conference," said Haye.
"He had his jaw wired. This is the guy who’s training him, so these are two idiots together, two buffoons."
