It started as a verbal spat and ended with the threat of gun violence and an arrest. Things, they can escalate quickly when fighters get their blood up.
And Dereck Chisora? His blood, it seems, is always up.
It was a tough week for Chisora. First he slapped Vitali Klitschko in the face as the two weighed in for a WBC title fight, costing himself a portion of his purse and a lot of respect.
"He hit me, not like a boxer but like a woman," Klitschko told the media.
Undaunted, with no lessons learned, Chisora caused mayhem before and after the fight, first spitting water at Team Klitschko as the fight began and again getting in Klitschko's face after losing a one-sided decision.
Amazingly, none of that is why he made this list. That happened after the fight when fellow boxer David Haye, looking to return to the ring, engaged both Chisora and the Klitschko camp in playful banter from the back of the room at the press conference. Chisora, however, was not amused, especially when Haye called him a loser.
"Tell that to my face," Chisora screamed, via Daily Mail. "I’m coming down, tell that to my face."
What followed can only be described as a donnybrook. Glass bottles, tripods and fists flew. A distraught Chisora was ready to take things even further.
"He glassed me. I swear to God, David, I am going to shoot you," he yelled. "I am going to shoot you. I am going to physically shoot David Haye."
As Chisora was led from the building, Haye got the last word, refrencing his rival's three consecutive losses in the ring.
"That's four in a row now!"
Five months later, Haye would again have the last word, this time in the ring, knocking Chisora out in five. The two then ended their feud with a handshake and a hug.
All's well, I guess, that ends well.
