It's just over two weeks until the first ever unified world heavyweight title fight takes place in Great Britain, as Anthony Joshua meets Joseph Parker.
It's set to be yet another sell-out crowd for the Olympic gold medalist, who steps into the ring at the Principality Stadium in Cardiff once more, having knocked out Carlos Takam there in October.
But there is a lot more at stake this time, with Joshua looking to take Parker's WBO belt, putting his IBF, WBA and IBO titles on the line.
It is set to be an absolute cracker, and both fighters are predicting that it won't go the distance, something which AJ of course has never done.
He's won all 20 of his professional bouts by knock out, though Carlos Takam and Wladimir Klitschko pushed him close to the full 12 rounds in his last two.
Whoever wins is likely to want to take on Deontay Wilder for his WBC world belt in order to become the undisputed heavyweight champion of the world.
'The Bronze Bomber' suffered a real scare against Luis Ortiz almost a fortnight ago, but eventually knocked his opponent out in the 10th round to take his own record to 40-0, with 39 inside the distance.
However, Joshua's promoter Eddie Hearn has predicted it will be almost impossible for his fighter to achieve such a feat.
Hearn revealed that AJ will have just a year to fight Wilder, if he gets past Parker, but certain factors are likely to make that very difficult.
The Briton would have to fight mandatories before he could meet the American, and if he doesn't do that within a year he would be forced to vacate some of his belts.
"There’s going to be very limited opportunities to become the undisputed heavyweight champion of the world," he admitted.
"With all the mandatory fights - and with everything else - you’re probably only going to get one shot in three or five years and that is about this time if he beats Parker.
"So he has to fight Wilder in the next 12 months maximum to get the undisputed title otherwise it won’t be possible.
"When he wins the undisputed title he’ll probably have to vacate a load.
"But at least he has done it. He has become the undisputed heavyweight champion of the world and that is the ultimate goal."
That is unfortunate news for Joshua and his masses of fans, as it would mean rushing several fights in a small time frame if he is to do it.
Given his power though, you wouldn't be surprised if he muscled his way through the field to create history.
