Tom Aspinall, the UFC's interim heavyweight champion, will not take another fight under his existing contract if he follows the counsel of Eddie Hearn, who signed Aspinall this February as the inaugural client of Matchroom Talent Agency. Hearn disclosed the stance in a Thursday interview, marking the first public contract dispute between his four-month-old management firm and the UFC.
Aspinall holds the interim heavyweight title after his 57-second knockout of Sergei Pavlovich in November 2023, then defended it with a 69-second finish of Curtis Blaydes in July 2024. His current deal, signed before either of those performances, pays a reported base of $500,000 per fight with standard pay-per-view escalators that activate above 350,000 buys. Jon Jones, the undisputed champion whom Aspinall has publicly chased for fifteen months, operates under a 2023 extension worth approximately $8 million per bout when PPV thresholds clear. The gap explains Hearn's calculus.
Hearn launched Matchroom MMA in February with Aspinall as the anchor client alongside four lesser-ranked UFC fighters and two Bellator veterans. The agency operates under the Matchroom Sports umbrella, which manages 180 boxers globally and produced 42 title fights in 2024. Boxing promoters routinely renegotiate fighter contracts mid-term when a talent's market value visibly exceeds their paper rate; UFC president Dana White has historically resisted that pattern, holding athletes to their signed terms even when subsequent wins triple their leverage. White told reporters in March that Aspinall would fight Jones by November 2026 if Jones defeats Stipe Miocic at UFC 313 in August. That timeline assumes Aspinall fights under his current structure.
The UFC model binds fighters to multi-fight deals with automatic extensions triggered by title defenses. Aspinall's contract, signed in early 2023, runs through four more fights or until he loses his title and leaves the organization. Champions cannot become free agents by running out their bouts; they renew with each defense. Hearn's public positioning suggests he wants the UFC to tear up the existing paper and write new terms before Aspinall enters the cage again. The alternative is Aspinall sits idle while the UFC books Jones or strips Aspinall of the interim belt, forfeiting his negotiating position.
Matchroom's revenue model in boxing relies on co-promotion deals where the fighter and manager share upside from ticket sales, international broadcast rights, and sponsorship inventory the fighter controls. UFC fighters surrender nearly all ancillary revenue to the organization in exchange for fixed purses and PPV points. Hearn told *The MMA Hour* in March that he would "educate" UFC fighters on "what they're worth." The Aspinall standoff is that education in practice. If Hearn forces a renegotiation, other managers with title-level clients will note the tactic. If the UFC waits him out or strips the belt, Hearn's MMA agency loses credibility before its first anniversary.
The immediate test is UFC 313 on August 9, where Jones defends against Miocic in Las Vegas. If Jones wins, White has said he wants the Aspinall unification fight on a November card in London or Manchester, where Aspinall could anchor a gate worth $15 million to $20 million in a soccer stadium. That event's success depends on Aspinall being available. Hearn's February pitch to prospective MMA clients emphasized his ability to leverage boxing relationships with DAZN and Sky Sports to create bidding tension the UFC rarely faces. Aspinall sitting out his contract is the leverage demonstration.
The UFC's standard response to public contract disputes is silence followed by matchmaking around the problem. The organization stripped Colby Covington of an interim welterweight title in 2018 after he declined a fight during contract negotiations, then waited eleven months to re-book him at a lower interim rank. Aspinall's leverage is heavier: he is British, 31 years old, and finishing top contenders in under ninety seconds while Jones ages into his final fight. The UK market drove $47 million in UFC ticket revenue in 2024 across three events. Aspinall headlines all future UK cards if he stays active.
Hearn meets with UFC executives in Las Vegas the week of August 5, three days before Jones-Miocic. That meeting will clarify whether Matchroom's MMA venture operates inside the UFC's existing contract structure or attempts to break it. Aspinall's next fight, whenever it occurs, sets the terms for how the next generation of British fighters negotiates with the promotion.
No interim champion has successfully forced a mid-contract renegotiation in UFC history. Hearn is betting Aspinall's finishing rate and the London stadium calculus change that pattern.
The takeaway
Aspinall holds out for new UFC terms under Hearn's advice, testing whether heavyweight star power can break the promotion's contract discipline before a potential Jones unification.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.
