It will be Carlos Takam, and not Kubrat Pulev, who tries to defeat Anthony Joshua on October 28.
Over 70,000 fans have already bought tickets to see AJ in action in Cardiff, though they will have been expecting to see him go up against the Bulgarian.
Following Pulev's decision to withdraw with a shoulder injury, he has been replaced by the 36-year-old Frenchman.
Joshua will be looking to carry on his impressive record of 19 knockouts in 19 bouts, even if his preparation has been somewhat disrupted by the last-minute change.
Indeed, he may have initially been gearing up for another clash with Wladimir Klitschko; in his last outing, he took the WBA heavyweight title off the veteran fighter, whose retirement has scuppered any hopes of a rematch.
Fortunately, it appears he has long had eyes on Takam and knows exactly what to expect from him.
“I have known about Carlos Takam for a long time, he is well rounded and has been moving up the IBF rankings," he said, per the Sun.
“He’s strong, he's from Africa and he's game, he has had one world-title shot and some people don’t make the same mistake twice. This is his chance to shock the world.
“Takam is already as tough as they come, he walks forward and that is disheartening for a fighter to see - I want to see what fire he will walk through to get this belt.
When the question was put to him how long it'll take him to dispense with his new rival, he added:
“People are asking me what round and I say 10-12 because this guy’s head is like a block of cement.
“I like Takam because he moves well and likes to box, and then, later on, he likes to plant his feet and trade.
“I have had sparring partners coming in to try to knock me out and I have had to hit them with a body shot, so that will help.
“I think he’s durable and he’ll be even more durable because is not favourite and he is in hospitable surroundings."
No man has yet managed to go the distance with the former Olympic champion, so it will be pretty admirable if Takam does last until the later rounds.
Klitschko has taken him the furthest in what was arguably the biggest test of his credentials so far.
Takam could have a long night ahead of him.
