Anthony Joshua's promoter Eddie Hearn has shared how the four-belt heavyweight reacted after seeing a planned unification bout with Tyson Fury collapse.

The two Brits were due to go toe-to-toe in Saudi Arabia this summer but plans were scrapped after an American court ruled that Deontay Wilder could have his rematch with the Gypsy King.

That trilogy bout is due to take place on October 9th, while Joshua returns to the ring on Saturday evening to face mandatory challenger Oleksandr Usyk.

However, that fight was also subject to changes as it was pushed back from an original date of August 14th as AJ adjusted to the blow of the Fury bout being off.

"It was difficult [to refocus] after the Fury fight fell through and that's why AJ took his time. And I think if he were to have stuck to that original date of August 14, I think it would have been a big mistake because obviously he'd been training since January after the Pulev fight for Tyson Fury," he told digital sports PR agency Press Box PR.

"And when that fell through, it was a blow for everybody. So rather than sticking to that date, he said: 'no, let me just get my head around this.' Have a couple of weeks off. Let's reset training camp. Obviously we needed to change the style of training. We needed to change the sparring partners.

"And he got the camp absolutely perfectly right. And when he went back into camp he'd forgotten all about the Tyson Fury fight. And that was so important to make sure that he was comfortable with who he was fighting."

Hearn also explained how AJ has matured with age and experience to become a more tactical fighter, backing the Brit to win on Saturday night.

"Joshua doesn't fight in a specific way anymore. You know, when he was inexperienced, when he didn't really know what he was doing, he would just be very aggressive and beat people up. He still beats people up, but he probably does it a little bit smarter now. And I think in this fight, he needs to do just that. He needs to beat up Usyk in a smart way. You're not going to see him rush out in the first round throwing windmills.

"That's not his style. He wants to show that he has the skill to beat Usyk, as well as his strength and size and power. This is a really tough fight. You know, whenever you fight someone with no fear of losing it's a tough fight, especially when they've got the skill that Usyk has.

"We know we're going to get the very best Usyk on Saturday night. I think it's going to take a great performance from Joshua to win."
