WBC cruiserweight world champion Tony Bellew believes David Haye is bad for the sport.

The two domestic rivals will collide on March 4th at the O2 Arena in London. Sky Sports Box Office will carry the anticipated showdown.

Bellew called Haye a "disgrace to boxing" for his pre-fight threats. The two boxers scuffled at their kickoff press conference in November and there was more physical drama when they came together at the Sky Sports studios to film "The Gloves Are Of."

Haye, a former two division world champion, broke a layoff of more than three years last January. Bellew is moving up to the heavyweight division to face him.

In the last few weeks leading up to the fight, Haye has continuously promised a brutal and violent ending for Bellew next Saturday night.

"He's a disgrace. It's not the way we want our sport to be perceived. We're not in the dark ages. I'm trying to give it a good image. I'm not the best one to do it, because I've done some stupid things. I only speak the truth. He's just an idiot, he doesn't think before he speaks," Bellew told Sky Sports.

"I've got no malice or real nastiness in me to say these vicious, horrible things. He carries the sport in a bad way. I'm not saying I'm a saint by any stretch of the imagination, because I'm not, but I'm nowhere near this clown's level. He is just a disgrace to boxing."

Bellew is not lacking any confidence. Almost universally viewed as a huge underdog, Bellew feels very good about the possibility of shattering Haye's ego with an unexpected loss.

"If he loses to me, it will be the worst thing that has ever happened to him," said Bellew. "But like I say, I'll give him the rematch. If he loses to me, his rep and his ego have just been eaten, and I'll enjoy it when I put salt and pepper on them after I've finished."
