Anthony Joshua will now defend his IBF and WBA world heavyweight titles against Carlos Takam on October 28 at Cardiff's Principality Stadium.
Kubrat Pulev was meant to be the Brit's next opponent but was forced to pull out due to suffering a shoulder injury in training.
Joshua reportedly isn't too phased by having to fight Takam instead of Pulev, although he was "p****d off" at the time of hearing the news.
That's according to Eddie Hearn, who claims AJ will need to prepare for what will be an entirely different challenge to Pulev.
"Takam is a durable rough-house fighter who puts on a lot of pressure," said Hearn. "He is relentless. He'll run through walls for this one.
"Anthony, though, has been preparing for a completely different challenge. He has spent nine weeks working towards meeting a 6ft 5in stand-up style of fighter in Pulev.
"Now he’s got to get ready for a 6ft 1in scrapper who loves to fight inside and swings big ones over the top. It’s completely different."
Takam has a track record of taking fights into the latter rounds, whereas Joshua will want to end the bought as soon as possible.
But if they do go the distance later this month, it's not as if Joshua hasn't been pushed to his very limit before.
Back in April, Joshua went 11 rounds with Wladimir Klitschko in what was undoubtedly his toughest fight as a professional boxer.
Despite taking a battering, Klitschko recovered time and time again, only for the referee to award Joshua victory by TKO in the second-to-last round.
Joshua will use the experience at Wembley to ensure victory over Takam and it's pretty clear he remembers every second against Klitschko.
A BBC documentary called, "Anthony Joshua: The Fight of My Life," will air tomorrow night and it features an amazing segment where AJ relives fighting Klitschko in the ring.
In the video, Joshua reflects on moments like when he thought he had Klitschko in the fifth round, only to realise the Ukrainian - who he describes as a "Terminator" - was back on his feet.
The 28-year-old also discusses telling Klitschko in the sixth round that if he allowed him to get to the seventh, he was going go to "knock [him] the f*** out". Check it out.
