LONDON, England — It was while Daniel Dubois was deep in the trenches against American heavyweight Jarrell Miller that his promoter Frank Warren decided enough was enough.

Though it was still early in the contest, Miller had absorbed much of what Dubois launched at him and continued to plod forward against the despondent Brit.

It was then that Warren shot his eyes towards Dubois' dad, Stanley, at ringside and grabbed him before shoving him into his son's corner to aide trainer Don Charles in barking instructions through the ropes.

"If you can't do it for your dad, who can you do it for?" Dubois says with a smile as he recalls the moment in question at a media day in London on Oleksandr Usyk fight week.

Several rounds later Dubois, four months after losing to Usyk, became the first to stop Miller.

"And he's been in the corner since, hasn't he?" Warren says.

"Yeah, that's right," Dubois responds.

Later today, IBF champion Dubois (22-2, 21 KOs) faces The Ring, WBC, WBA and WBO champion Usyk (23-0, 14 KOs) again for all the marbles at Wembley Stadium in London. Around 90,000 people will be in attendance and the fight will be streamed live on DAZN PPV.

Dubois hasn't had it all his own way over the last five years, but since the Miller fight he has also picked up victories over Filip Hrgovic and Anthony Joshua.

The Joshua fight was a crowning moment. It was supposed to be AJ's return to the heavyweight throne. Three-time heavyweight champion. But Dubois dominated in thrilling style, dropping British boxing's poster boy several times before landing a howitzer which sent the much-loved figure hurtling face-first into the bottom rope.

As Boney M's "Daddy Cool" blared out over the stadium speakers in the immediate aftermath, Dubois trudged about the ring and fist-bumped every member of his team without breaking a smile. This was supposed to happen, but not many believed it would.

The case is the same for tonight's historic fight, the first four-belt undisputed heavyweight title fight to take place on British soil.

The undefeated Usyk, a two-time undisputed champion himself, remains a wide favourite, and rightly so. But Dubois is adamant on causing disruptive chaos. Stanley predicted his son would be in this position before he was born, and from the moment he exited the womb, a plan was put in place to ensure those premonitions would come true.

"It's wonderful to know that your dreams can manifest into reality," Dubois Sr tells The Ring. "I was saying that while he was in the belly he was going to be world champion. And then when he was born, he was born with so much muscle. I'm like, 'Wow, is that normal?'

"He just was so defined, like he'd been in the gym already. If there was ever any sign, that was definitely a sign. So I thought 'He's built for it, let's go for it.'"

By the age of five, Project World Champion had begun.

"My dad had a dream and he passed it on to me," Dubois says to The Ring.

"He took me to the gym and I was like 'Wow, is this real?' There were kids sparring and skipping and I just thought 'Wow, I want to do that'. I found it really awesome, to be honest."

So, with young Daniel, the sixth of Stanley's 11 children, fully on board, things kept rolling.

"I've been very hardworking all through my life, so I was able to be consistent with him early, because I was consistent with myself," Dubois Sr adds.

"No one taught me or gave me any guidance. I was just blessed that Daniel was able to understand what you need to do, which was get up early and work. The early bird catches all the worms, I've always had that motto, and I passed it onto him. Once I started training him, I sort of lost interest in my own business and all what I was doing. I just let it sort of fade away and I put all my effort into Daniel.

"He was a lovely child, he never rebelled against me or questioned what I was doing. He always did what I told him to. He was homeschooled so I was his teacher, his father and his leader, he didn't really know how to rebel. If he did rebel, it wouldn't have been worth it because he wouldn't be where he is now. It's paid off for him because he's very successful now."

Dubois also insists that he could've done anything he put his mind to, as being active was the be-all and end-all throughout his extraordinary childhood.

"I'm not really an academic type of guy like that," the 27-year-old explains. "But I love sports, I've been training in all kinds of sports from an early age. My dad took us down to Crystal Palace, we did a lot of javelin, athletics, swimming, I even tried gymnastics.

"My dad said I could be a world champion when I was young, so to get here now, it's been a long journey, a long road, a lot of sacrifice, a lot of things have happened, but I'm glad we're here."

"I raised him like a machine," his father says.

Back to that moment in Riyadh on Dec. 23, 2023, when Warren pulled ace card Stanley from his sleeve:

"Frank didn't realise how nervous he was making me, putting me up there. And he actually helped me to deal with my own fears and anxieties. I overcame them. And maybe by overcoming them, Daniel overcame his."

The build-up to Usyk II has been fiercer than it was last time. There have been plenty of jibes from Team Dubois about the much-talked about body-shot-low-blow from the first encounter. The retort from the Ukrainian's side has been that all Usyk needed to do was use his jab and the fight, which ended in the ninth round, was a simple one.

Dubois pushed Usyk when the two met in April and then roared in his face when they faced off Tuesday before doing the same at Thursday's press conference. He has shown he's up for it like never before.

"It's time to turn up the heat and bring the chaos," he says. "I'm going to restore order with victory."

Victory would be right up there with one of the biggest and most famous in British boxing history, and on home turf at the National Stadium, no less.

"It's for four belts, no one [in Britain] has ever done it," says Warren when he's asked about the potential achievement ranking above anything Joshua and Tyson Fury have accomplished in the sport.

"He's got to believe."

Dubois chimes in. "You believed in me, Frank, didn't you?"

"That's why we signed you, yeah," comes the Hall of Fame promoter's reply.

"Destiny" is the word which has been used by Dubois' trainer Charles, who linked up with the Londoner just 14 weeks before the first Usyk fight. Though the dreams Stanley had for his son have already come true, a win over an unbeaten, modern great in Usyk will supersede those wild visions he had in 1997.

"It's all about timing," he says. "God willing, Daniel deals with him. I'm sure he'll shock the world and shock himself.

"It will be a great fight and a great victory for Daniel Dubois."
