Murat Gassiev returns to Moscow for a homecoming that should have been a blockbuster. His first WBA World Heavyweight Championship defence was supposed to be against Tony Yoka — 2016 Olympic super-heavyweight gold medallist, former European heavyweight champion, and one of boxing’s most marketable names. Instead, Yoka suffered a back injury in training and withdrew on July 2, just nine days before fight night, leaving Peter Kadiru — unranked by the WBA, a relative unknown to casual fans — to step in as the replacement. The title is still very real. The occasion at VTB Arena on Saturday, July 11 is still enormous. But the controversy of a first heavyweight title defence against an unranked late substitute casts a long shadow over the evening.
For Gassiev, the bigger picture deserves to be celebrated regardless of opponent. He joins an extraordinarily exclusive club — only Evander Holyfield, David Haye, and Oleksandr Usyk before him have unified the cruiserweight world titles and gone on to win a world heavyweight championship. Whatever the circumstances around July 11, that achievement is permanent.
Murat Gassiev (33-2, 26 KOs) is the most decorated heavyweight in Russia and one of the most complete big men in world boxing. The 32-year-old from Vladikavkaz built his reputation in the cruiserweight division, winning the IBF title in 2016 and then entering the World Boxing Super Series — the WBSS “Ali Trophy” — cruiserweight tournament. He dismantled Krzysztof Glowacki, Mairis Briedis, and Yunier Dorticos before meeting Oleksandr Usyk in the final. The loss to a man who would go on to become undisputed heavyweight champion is no embarrassment.
His heavyweight transition began in 2020 and suffered one wobble — a split decision loss to Otto Wallin in September 2023. The response since then has been emphatic: three successive finishes capped by the December 2025 masterclass in Dubai where he feinted Kubrat Pulev perfectly and launched a walk-off left hook that ended the fight in round six, claiming the WBA Regular heavyweight belt. When Oleksandr Usyk vacated the full WBA title in 2026, Gassiev was elevated to undisputed WBA World Champion. His 26 knockouts from 35 fights — a 74% KO rate — mark him as a genuine power puncher with the combination-setting craft to unlock any defence.
Peter Kadiru (23-1, 13 KOs) answered the phone when Yoka’s team called and deserves credit for that alone. The 28-year-old German — raised in Hamburg with Nigerian heritage — is no novice: he won gold at the 2014 Youth Olympics and the 2014 Youth World Championships as an amateur before turning professional in 2019. His sole defeat came via KO against the heavy-handed Marcos Antonio Aumada.
His most recent win — a unanimous decision over former bridgerweight title challenger Senad Gashi in May 2026 — earned him the WBA Continental heavyweight title and represents his best professional performance. What makes the booking contentious is that Kadiru carries none of the WBA heavyweight rankings and had just nine days to prepare for the world champion in that champion’s home city. He is tailor-made for the “nothing to lose” narrative that occasionally produces the biggest upsets in boxing.
Physically, he is marginally bigger than Gassiev — a shade taller at 6’4” to 6’3.5” — with comparable reach. On paper, Gassiev has everything else: the title, the power record, the experience, the home crowd.

This fight is built around one central question: can Kadiru’s ranginess and jab keep Gassiev honest, or does the champion’s elite combination-setting craft close that marginal physical gap and bring his power into play?
Gassiev is a feinter and a combination builder — the Pulev KO is the blueprint. He doesn’t bludgeon opponents into submission; he sets them up, reads their rhythm, and then fires. His cruiserweight career gave him footwork and counter-punching instincts that most heavyweights simply don’t possess. Kadiru, by contrast, is a points accumulator — solid behind his jab, disciplined at distance, but with a 57% KO rate that suggests he wins fights rather than ends them. His three-consecutive-UD victories against modest opposition raise a question mark over whether he has the volume or punch output to threaten Gassiev.
The danger for the champion: over-confidence. A nine-day replacement can carry a surprise. Kadiru’s slight height edge means Gassiev must work to get under his jab — and in the moments he doesn’t, he may take cleaner shots than he budgeted for.
Gassiev:
Kadiru:
Odds had not been published at time of writing given the late replacement, but Gassiev is expected to open around -600 to -800 (1/6 to 1/8 fractional). Kadiru as the unranked short-notice challenger will be a major outsider.
This fight is straightforward on paper. Gassiev is a pound-for-pound quality operator defending a world title at home against an unranked opponent who had nine days’ notice. The Pulev KO showed exactly what he is capable of when he has the patience and craft to set his moments up — and nothing in Kadiru’s record suggests he can survive the second half of a 12-round heavyweight title fight at this level.
Prediction: Murat Gassiev by TKO, rounds 7-10. Expect Kadiru to be competitive through the middle rounds before Gassiev’s combinations take their toll.
