Oktagon 89 has its main event locked in, with former UFC fighters Zhalgas Zhumagulov and Igor Severino set to collide for the Oktagon bantamweight championship on June 6 in Bratislava.

Zhumagulov, 37, brings a wealth of experience to the headliner. The Kazakhstani fighter, who trains out of American Top Team, holds a professional record of 14-9 and competes as a switch-stance striker standing five-foot-four with a 66-inch reach. He averages 5.24 significant strikes per minute at 43 percent accuracy, and adds a modest grappling dimension with 1.3 takedowns per 15 minutes.
Severino enters as the younger and physically larger man at just 23 years old. The Brazilian out of Chute Boxe Joao Emilio carries an imposing 8-1 record and stands five-foot-seven with a 69-inch reach. His striking output is striking in its own right — 7.17 significant strikes per minute at 52 percent accuracy — and his grappling numbers are exceptional, averaging 9.69 takedowns per 15 minutes in his career.

Why it matters
- The bout serves as a title fight, meaning the winner walks away as Oktagon bantamweight champion.
- Both men carry UFC experience, raising the profile of the matchup within the European promotion.
- Stylistically, Zhumagulov's volume striking meets a fighter in Severino who is both a high-output striker and an elite-level takedown artist, creating clear contrasts in approach.
- At 37 versus 23, the experience gap between the two is matched by a significant difference in trajectory, giving the fight added narrative weight at 135 pounds.
