He's been a world heavyweight champion for two years now, and Anthony Joshua shows no signs of slowing down.

Dominic Breazeale, Eric Molina, Wladimir Klitscho, Carlos Takam and Joseph Parker have all fallen to the Brit since he won his first championship against Charles Parker in April 2016.

Negotiations remain ongoing with the 'Bronze Bomber' Deontay Wilder in regards to a huge unification fight, likely to take place at the end of 2018, or early 2019.

Joshua's promoter Eddie Hearn confirmed that an October or November fight is the most likely scenario, with IBF contender Alexander Povetkin waiting in the wings should the Wilder talks collapse.

But 'AJ' isn't guaranteed to stay in the sport forever.

Joshua revealed he was keen to try his hand at MMA somewhere down the line, with Francis Ngannou and Jon Jones two fighters he'd like to step into the octagon with.

UFC owners WWE-IMG have also applied for a license to promote boxing events in the state of Nevada, which could mean if Joshua were to jump ship he could be starring in big-money Las Vegas clashes, without having to switch sports.

Reports circulated that White was going to offer Joshua a $500 million contract, but the UFC president denied this was ever the case, before questioning Hearn's character.

"It's not true," said White to MMA Roasted in regards to the alleged offer. "Me and Joshua spoke on the phone. We never got together.

"His contract was coming up and I said, 'Listen, I would like to talk to you guys.'

"He made it very clear to me that he wasn't going to leave Eddie and that he wanted to stay with Eddie.

"I said: 'Yeah, I'm not looking for you to leave Eddie, we can all work together, I think we can do a lot for you here in the United States.'

"Eddie Hearn hasn't been in the business that long. I think Eddie Hearn was very oversensitive over the thought that Anthony Joshua and I would even talk and was almost insulted by it.

"And that really wasn't the conversation we had or the intent."

If these comments towards Hearn by White cause a war-of-words between the two promotors, we could be in for some juicy sound bites from both sides of the Atlantic.

For now though, all eyes are waiting on Joshua and Wilder to seal the deal on what would be the biggest heavyweight fight for some time.
