Kell Brook and Gennady Golovkin have agreed to arguably, the biggest fight of the year when they collide in London on September 10.
Neither man has been beaten so far during their title-laden careers and the pair have amassed 57 knockouts between them.
It looked all but certain that Chris Eubank Jr would be the man to face the feared Kazakhstani for his undisputed world middleweight titles, but the deal fell through after the Eubank camp made some unreasonable demands.

Special K will be stepping up two weight divisions to take this fight and with GGG's world-renowned knockout power, the fight has been widely perceived as an uphill struggle for Brook.
However, when the opportunity presented itself in light of the Eubanks' surprising stance, the impressive IBF welterweight champion simply couldn't ignore the chance.
"The greats have gone on, like Sugar Ray Leonard, to win titles in the heavier divisions," said Brook.
"To be a great fighter, you have to do great things. For me, a welterweight, to step up against one of the most feared fighters in the world, I'll have to do everything right. If I don't, I'll come up short."
Sheffield-born Brook has a pristine record of 36 wins from 36 bouts and has certainly earned his chance at a huge fight like this. He's well aware of what he'll have to go through if he wants a historic result.
"We're going to put the hard work in in training. We will go through hell in that training camp but that's what you have to do to reach greatness.
"When it was floated, I jumped at the chance. I'm doing it for the fans."
Too often, boxers dodge fights that might hurt their credibility or aren't deemed a safe bet. Nobody can accuse Brook of that with this upcoming war and he will hope his bravery is rewarded with a win.
