Oktagon 89 will feature a bantamweight title fight between two former UFC fighters when Zhalgas Zhumagulov meets Igor Severino in the main event on June 6 in Bratislava. The promotion's bantamweight championship is on the line in what shapes up as a compelling clash of experience against youth.
Zhumagulov, 37, brings a career record of 14-9 to the cage representing Kazakhstan out of American Top Team. The switch-stance bantamweight stands five-foot-four with a 66-inch reach and has shown consistent volume striking throughout his career, averaging 5.24 significant strikes landed per minute at 43 percent accuracy. He also contributes on the mat, averaging 1.3 takedowns per 15 minutes.
Severino enters at just 23 years old with a record of 8-1, representing Brazil under the Chute Boxe Joao Emilio banner. The orthodox fighter stands five-foot-seven with a 69-inch reach and carries striking numbers that stand out even at the elite level — 7.17 significant strikes landed per minute at an impressive 52 percent accuracy. He also offers a serious grappling threat, averaging a remarkable 9.69 takedown attempts per 15 minutes.
Why it matters
- Both men are former UFC competitors looking to capture gold in a rival promotion, giving the bout added narrative weight.
- A Severino victory would make one of the sport's youngest contenders a champion at just 23; a Zhumagulov win would reward a veteran of nearly a decade and a half in professional MMA.
- Stylistically, Zhumagulov's switch-stance versatility and ring experience contrast sharply with Severino's relentless pressure, high-volume striking, and elite takedown activity.
- The result will define the bantamweight picture at Oktagon heading into the second half of 2026.
