Daniel Dubois, 20-2 (19 KOs) enjoyed a coming-of-age moment against Jarrell Miller last December. The 26-year-old showed the mentality to bite down on his mouthpiece and fight through adversity before landing a 10th and final-round stoppage against the American.

According to some pundits, Dubois was fighting to save his career at the top tier having suffered a conclusive stoppage defeat to Oleksandr Usyk in August.

The accusations landed at Dubois's feet not only following his defeat to Usyk but also years prior, when defeated by 2016 Olympic silver medalist Joe Joyce in 2020.

The aftermath was a painful one for Dubois, who had sustained a fractured socket during the fight, which needed surgery along with his heart and desire being questioned by the public, media members, and fighters who believed he took the easy way out.

Dubois attended Monday's press conference, which unveiled the participants of June 1’s Matchroom vs. Queensberry bill, where five of Matchroom’s fighters will square off against five of Queensberry’s.

The 5 vs 5 will be the undercard to the anticipated light-heavyweight undisputed title fight between Artur Beterbiev and Dmitrii Bivol in Riyadh, Saudi Arabia.

Dubois will feature in a prominent fight on the bill against Olympic bronze medalist and the IBF's No. 1 rated contender Filip Hrgovic, 17-0 (14 KOs).

Dubois spoke briefly at the press conference and mentioned he and Hrgovic had shared rounds in sparring, telling Hrgovic that he had subsequently improved. Hrgovic replied saying he “hoped that he [Dubois] has improved because the sparring did not go so well for him.”

Speaking to IFL TV, Dubois admitted that the sparring with Hrgovic had been hard and that the Croat was a ‘f******’ tough guy to come up against.

“It was a hard spar. ‘This kid [Hrgovic] was f****** tough,” Dubois said.

"That’s sparring, it’s irrelevant, really. Let’s go. I'm ready for a fight.”

In an interview following Monday's press conference, Hrgovic claimed that if he was defeated by former world title challenger Dubois, he would hang up his gloves and walk away from the sport.

Upon hearing Hrgovic’s self-given ultimatum, Dubois promised to send the Olympic bronze medalist into retirement.

“If he’s going to retire, let him retire. I’ll retire him,” added Dubois.

“I did a job on [Jarrell] ‘Big Baby’ [Miller], and now I have to do a job on him [Hrgovic]. On paper, it’s a harder fight [than Miller], but in reality, with what I can do when I get in there, I can make it an easier fight for myself just by being on form. I need to be on form and stay in the right mind.”
