Overview
- The Moscow bout on Saturday ended in a sixth-round technical knockout when Kadiru’s trainer Christian Morales threw in the towel to protect his fighter and Gassiev retained the WBA belt.
- Kadiru took the fight on very short notice after Tony Yoka withdrew with a back injury and entered without the typical multiweek world-title camp.
- Reports say Kadiru secured a Russian visa in Berlin midweek and flew with his Ringside Zone team via Istanbul to make the unexpected trip to Moscow.
- The match existed because Oleksandr Usyk relinquished heavyweight belts earlier in 2026, a move that led the WBA to elevate Murat Gassiev and opened late opportunities for challengers.
- Kadiru posted on Instagram accepting the loss, vowed to learn and continue his career, and the stoppage has prompted debate about fighter safety, venue choice and the depth of German heavyweight boxing.
