HrgoviÄ vs Itauma in London: IBF title, 13-year age gap and tension that exploded at the weigh-in
Filip HrgoviÄ and Moses Itauma enter a showdown at London's O2 Arena on 29 August 2026 that will determine the new IBF heavyweight world champion. For 34-year-old HrgoviÄ, this is his first opportunity to win a full world title, while 21-year-old Itauma is trying to confirm his status as one of the most exciting young heavyweights and become the second-youngest world champion in the division's history. According to data from promotional company Queensberry, HrgoviÄ enters the fight with a professional record of 20 wins and one loss, including 15 stoppage victories, while Itauma is unbeaten with 14 wins, 12 of them achieved before the final bell. Ahead of the fight, however, the greatest attention was drawn not by the statistics but by an incident at the official weigh-in, when Itauma pushed HrgoviÄ off the stage and the Croatian heavyweight immediately returned and struck him with an open hand. Security personnel and team members had to separate them, so the final face-to-face meeting turned what had until then been mostly a verbal rivalry into a physical confrontation.
The main event takes place at The O2 in Greenwich, the large London arena that has hosted a series of major boxing nights in recent years. The venue's official website confirms that the HrgoviÄ - Itauma fight is scheduled for Saturday, 29 August, while organizer Queensberry is promoting the event under the name "Natural Born Thriller". This is an event with consequences far broader than just another attractive heavyweight fight: the IBF belt is vacant, and the winner will immediately earn a place at the very top of one of boxing's most important and commercially followed divisions. For spectators traveling to London for the event, Greenwich and the wider eastern part of the city offer numerous options, and a useful overview can be found through accommodation offers in London near the event venue. In sporting terms, however, everything comes down to whether HrgoviÄ's experience can survive Itauma's speed, explosiveness and aggressive approach to the fight.
The weigh-in ended with shoving, a fall from the stage and a slap
The official weigh-in was held on 28 August, the day before the fight, and according to reports from Sky Sports and The Ring, both heavyweights made weight without any problems. Itauma weighed 241.7 pounds, approximately 109.6 kilograms, while HrgoviÄ came in at 236.2 pounds, around 107.1 kilograms. Both were lighter than in their previous appearances, immediately prompting assessments that they wanted to preserve as much speed and mobility as possible in a fight in which pace could be just as important as raw power. After the weigh-in came the customary final "face-off", but the exchange of words quickly became more aggressive. According to footage and reports from the event at London's Spitalfields Market, Itauma at one point pushed HrgoviÄ from behind while he was turning toward the crowd and photographers, after which HrgoviÄ stepped down from the edge of the stage, returned and struck his opponent across the face with an open hand.
The incident lasted only a few seconds, but it was enough for security personnel, promoters and team members to step between the boxers. Itauma later admitted that he briefly lost his composure, while HrgoviÄ justified his reaction by saying that the first physical contact came from the other side. Promoter Frank Warren said Itauma's move surprised him, particularly because the young Briton had appeared calm for most of the week despite HrgoviÄ's provocations. In previous public appearances, HrgoviÄ had called his opponent an inexperienced "kid" and claimed that he intended to "smash" him, while Itauma generally dismissed such messages as childish teasing. The physical confrontation at the weigh-in therefore changed the tone of the final preparations and raised an additional question about whether the emotional tension would carry over into the opening rounds of the fight.
HrgoviÄ enters the biggest fight of his career after three consecutive wins
HrgoviÄ's road to this opportunity has been considerably longer than Itauma's. The Zagreb-born boxer has been a professional since 2017, and before that he built a strong amateur career: he won a bronze medal in the super-heavyweight division at the 2016 Olympic Games in Rio de Janeiro, became European amateur champion in 2015 and world junior champion in 2010. In his official profile, Queensberry also highlights his extensive experience in the World Series of Boxing, a competition that for years served as a bridge between traditional amateur and professional boxing. HrgoviÄ spent much of his professional career highly ranked by the IBF, but his path to a full world-title fight was slower than expected after early victories over Eric Molina, Rydell Booker, Zhilei Zhang and Demsey McKean. His only professional defeat came in June 2024 against Daniel Dubois, in a fight for the interim IBF title that was stopped in the eighth round after HrgoviÄ suffered severe cuts around his eyes.
After that defeat, HrgoviÄ rebuilt his position near the top of the heavyweight division with three consecutive victories. In April 2025, he defeated Joe Joyce by unanimous decision, four months later he beat David Adeleye on points as well, and in May 2026 he stopped Dave Allen in the third round. The latest victory was particularly important because it showed that, at the age of 34, HrgoviÄ can still impose a strong pace and finish a fight before the later rounds. His style is based on a solid front guard, a heavy right hand, physical strength and an ability to take punches, but against Itauma he will have to be more disciplined when exiting his attacks because he is facing a much faster, more mobile southpaw. HrgoviÄ's main argument is not simply the number of professional rounds he has boxed, but the fact that he has already been through long and tactically demanding fights against world-class heavyweights.
Itauma reached a title fight after only 14 professional bouts
Itauma's rise is almost the opposite of HrgoviÄ's path. He was born in December 2004 in Slovakia, grew up in Kent, England, and entered professional boxing in 2023 at just 18 years of age. His official website lists a record of 14-0 with 12 stoppage victories, with the particularly striking statistic that he stopped eight opponents in the very first round. The quality of his opponents has gradually increased in recent years: in December 2024 he defeated Demsey McKean in the first round, in August 2025 he also stopped former world-title challenger Dillian Whyte in the first round, while in March 2026 he had to work until the fifth round against experienced Jermaine Franklin. That last fight in particular served as an important test because, for the first time against a tough and experienced opponent, Itauma had to maintain concentration, pace and distance control for a longer period.
What experts most often highlight about Itauma is not only his knockout power, but the unusual combination of foot speed, hand speed and defensive composure for a boxer of his size. Ahead of the fight, The Guardian reported assessments from former boxers and trainers who particularly emphasized his sense of distance, ability to change the angle of attack and unusually advanced tactical maturity. At the same time, precisely because of his short fights, one question remains that his professional career has not yet fully answered: how will the 21-year-old react if an opponent forces him through ten or twelve difficult rounds, if he takes a serious punch or if the original plan does not work. HrgoviÄ's camp believes that this is where the biggest opportunity for an upset lies. The longer the fight lasts, the more valuable the older boxer's experience could become, particularly if he manages to slow Itauma's footwork and force him into a physical close-range fight.
The IBF belt became available after Usyk's decision
The HrgoviÄ-Itauma fight was originally arranged as a major heavyweight contest with direct consequences for the top of the rankings, but at the beginning of August it was upgraded to a world-title fight. On 4 August, The Ring reported that the IBF had officially approved the pair to fight for the vacant belt after Oleksandr Usyk relinquished the IBF, WBA and WBC titles in June. The Ukrainian champion did not announce his retirement, but explained that he wanted to free up the belts and create opportunities for new fighters while retaining The Ring magazine title. That decision triggered a new reshuffling in the heavyweight division, where different organizations have separate rankings, mandatory challengers and rules. For HrgoviÄ, it meant that a fight he had already signed for suddenly became a contest for the title he had pursued for much of his professional career.
After Usyk relinquished the title, the IBF initially ordered a fight between Itauma and Cuban Frank Sanchez for the vacant championship. According to The Ring, Queensberry then arranged compensation for Sanchez's team to step aside and allow the already contracted Itauma - HrgoviÄ fight to become the title bout. Promoter Frank Warren stated that Sanchez should in return receive an opportunity against the winner in the first defense of the title. That means the winner of the London fight will not have much time to choose an easier next opponent, because alongside media attention and opportunities for major unification fights there will immediately be an obligation toward the IBF challenger. For both boxers, therefore, tonight's fight represents the beginning of a possible championship phase of their careers rather than the final point of a long climb.
Itauma can overtake Floyd Patterson on the historical list
The 13-year age difference is one of the most striking elements of the contest. If Itauma wins the IBF title on 29 August, he will be 21 years, eight months and one day old, which would make him the second-youngest world champion in heavyweight history. According to The Ring, the record is still held by Mike Tyson, who won the WBC title against Trevor Berbick in 1986 at the age of 20 years and four months. Second place currently belongs to Floyd Patterson, who in 1956, at the age of 21 and slightly short of his 22nd birthday, defeated Archie Moore. Itauma can no longer break Tyson's record, but a victory would push Patterson down to third place and make Itauma the youngest heavyweight champion in almost four decades.
The historical comparison, however, does not mean their careers can be compared directly. Modern professional boxing has four major sanctioning bodies, different mandatory challengers and a considerably more complicated title system than in Patterson's or even Tyson's era. Itauma himself previously said that, as a very young professional, he thought about Tyson's record, but later admitted that he realized how little control a boxer has over the scheduling of major fights and the decisions of organizations. Ahead of HrgoviÄ, he is therefore focusing on the specific opponent rather than historical statistics. That is also the greatest test of his reputation: so far he has moved convincingly through opponents, but for the first time he is facing an experienced heavyweight who has spent years ranked immediately below the very top of the world.
The key to the fight could be in the opening rounds
Itauma is a southpaw who relies on quickly entering range, changing angles and using combinations to force his opponent into passive defense. HrgoviÄ is a more traditional orthodox heavyweight, taller than many opponents and accustomed to physical fighting, but against Itauma he will have to be especially careful when exiting clinches and with the left hand coming from an awkward angle. The young Briton has made no secret during his career that he wants early stoppages, and eight first-round victories show how quickly he can punish a poor start. HrgoviÄ, on the other hand, says that the string of early knockouts does not impress him and that experience will become more important if he survives the initial onslaught. That clash of styles creates a simple but extremely tense tactical picture: Itauma will try to immediately establish speed and control of space, while HrgoviÄ must turn the fight into a longer, tougher and less orderly contest.
For HrgoviÄ, the opponent's body could be particularly important. If he can slow Itauma's movement with body punches and force him to stay in place for longer periods, he will create openings for the right hand and mid-range exchanges. But such a plan carries risk because every aggressive entry can leave an open line for Itauma's fast straight punch or left hook. On the other hand, Itauma has not yet had to prove that he can maintain the same intensity throughout an entire 12-round championship fight. HrgoviÄ's objective will therefore not simply be to "survive" the early pressure, but to gradually change the rhythm and force his younger opponent into situations he has rarely encountered in the professional ring.
O2 Arena gets a fight that could redirect the entire heavyweight division
For the London crowd, this is a night with a clear story of a generational clash, but its sporting significance goes beyond the local setting. Itauma represents a new generation of heavyweights trying to take over after a long period defined by names such as Oleksandr Usyk, Tyson Fury, Anthony Joshua and Deontay Wilder. HrgoviÄ belongs to an in-between generation that spent years close to the biggest belts but often had to wait for situations involving established champions and mandatory challengers to be resolved. Victory for the younger boxer would accelerate his path toward major unification fights and confirm that he is ready for the very top, while a HrgoviÄ triumph would be one of the biggest victories of his career and powerful evidence that experience can still stop the division's fastest-rising talent. In either case, the IBF will have a new champion who will immediately become an important part of the puzzle surrounding the future unification of the belts.
Until the fight begins, the question also remains whether the weigh-in incident will have any real effect on the tactics. Emotions in the heavyweight division can change a fight with a single reckless entry, and both men have enough power to punish a mistake. HrgoviÄ insisted throughout the week that Itauma's youth and reputation as a knockout artist do not impress him, while Itauma emphasized that he would not allow himself to be drawn away from his plan. After the shoving and slap, this is no longer only about words from a press conference. Inside the O2 Arena they will have to provide the answer between the ropes, and the winner will leave with the IBF title and a completely different place in the hierarchy of world heavyweight boxing.
