Weeks of speculation finally ended with an official announcement for October’s headliner. Jiri Prochazka will face Paulo Costa for interim light heavyweight gold. The bout headlines UFC 332 at Delta Center in Salt Lake City. That confirmation resolves one of the promotion’s more uncertain recent main event searches.

UFC 332 Prochazka Costa Interim Title Fight Confirmed
The promotion officially confirmed Prochazka against Costa for an interim championship bout. That title exists because current champion Carlos Ulberg remains sidelined with a torn ACL. Ulberg suffered that injury during his title winning knockout over Prochazka back in April. The division needed a path forward, and this matchup became the clear solution.
Costa steps up from middleweight to challenge for gold in a new division. He and Prochazka had already traded pointed comments online before the booking became official. Prochazka previously said the promotion offered him this fight for October or November. That public back and forth only added extra intrigue heading into the eventual announcement.
Key Details
Ulberg 15-1-0 is expected to remain out for the rest of the calendar year. That timeline left the light heavyweight division without a clear next step. Dana White had previously called an interim title genuinely possible during recent comments. This booking follows through on that earlier public suggestion from the promotion.
Reaction to the news has been mixed among fans following the division closely. Some questioned whether another interim title undermines the division’s overall credibility. Others viewed the matchup as a legitimate, exciting solution given Ulberg’s lengthy recovery timeline. Either way, the fight now gives fans a concrete main event to anticipate.

What This Means
The winner likely earns a future unification fight once Ulberg fully recovers from surgery. That stakes level gives October’s main event real championship significance despite the interim label. Both men now have a clear incentive to perform at their absolute best.
Costa’s move to light heavyweight adds a fresh dynamic to an already thin division. A win would instantly establish him as a serious threat in his new weight class. Prochazka, meanwhile, gets a direct chance to reclaim championship gold after his tough loss.
The card also features other significant action beyond just the new main event. Valentina Shevchenko defends her women’s flyweight title against Natalia Silva in the co main event. That pairing adds another genuine championship dynamic to an increasingly stacked October card.
Background Context
Prochazka and Costa have publicly sparred through interviews and social media in recent weeks. Costa previously competed as one of the sport’s most dangerous middleweight strikers. Prochazka remains a former champion himself, having briefly held UFC gold in 2022.
UFC 332 takes place October 3 at Delta Center in Salt Lake City, Utah. The event marks the promotion’s fifth visit to the city and first since 2024. Updates to the light heavyweight rankings picture will likely follow depending on October’s result.
Conclusion
UFC 332 Prochazka Costa booking finally gives fans a concrete main event to anticipate. The interim title stakes add real weight to an already compelling stylistic matchup. Both men enter with clear motivation given their recent career trajectories. Fans now count down toward October knowing exactly what is on the line.Â
