Dereck Chisora & David Haye could face lifetime boxing bans

Dereck Chisora and David Haye may face life bans for their Munich brawl says the British Boxing Board of Control General Secretary, Robert Smith.

"It's a possibility," Smith told BBC Radio 5 live. "The board have many powers. They can fine, they can suspend and they can withdraw a licence."

Haye and Chisora clashed after Chisora's defeat by defending WBC heavyweight champion Vitali Klitschko.

Chisora accused Haye of "glassing him", before saying at least four times that he would shoot the former WBA heavyweight champion.

He added: "If David don't fight me, I am going to physically burn him."

Chisora, a fully licensed professional boxer, will face a disciplinary hearing, Smith confirmed.
