Canelo Alvarez and Terence Crawford to fight for unique bonus in showdown

Either Canelo Alvarez or Terence Crawford will land a KO bonus if they can bring their mega-fight to an early finish.

Alvarez and Crawford will clash in Las Vegas on September 14 in one of the biggest fights in boxing history. Crawford is stepping up two weights to super-middleweight to take on the division's undisputed ruler. And while both men will cash a multi-million-dollar purse, there will also be an added incentive.

The fight will be promoted by UFC CEO Dana White whose promotion has long offered bonus for the fight and fighters of the night. And Saudi boxing supremo Turki Alalshikh is determined to weed out so-called 'Tom and Jerry' fights in which one fighter chases the other, and when asked how he plans to do that, he said: "We will not have them, that is the first thing. The second, for this fight and the next one, we will have a KO bonus."

Alvarez and Crawford came face to face in Riyadh on Friday night in the first of three press conferences ahead of their autumn showdown. Both men promised to deliver victory but declined to be drawn into a war of words. " He’s not going to beat me. Don’t worry about it," Canelo added. "I think this fight is going to be in the history books of boxing, that’s for sure. You’re nothing different. Nothing different."

Crawford responded: "For sure them belts are coming with me; they’re coming home with me. I’m taking them, and there ain’t nothing you’re going to be able to do about it come fight night. I promise you. "He's not going to beat me; don't worry about it...I'm a winner."

The September showdown will also have a record-breaking £140,000 Ring Magazine belt on the line. And Alvarez added: "He's a great fighter, but he's not Canelo. They only focus on my power, but I have more than that. This fight is going to be one of my best fights in my history."

Crawford added: "However I got to fight, I'm going to win. I'm not going to let someone else tell me how to fight when I've been doing that my whole life. I won't be running. I can tell you that. But I will be doing a lot of touching."
