The title fight was confirmed late Friday by UFC CEO Dana White on social media following the announcement that former champion Alex Pereira has officially vacated the 205-pound title as he potentially prepares to move up to the heavyweight division. Pereira’s decision opens the door for a new champion to enter one of the sport’s most exciting weight classes.
Jiri Prochazka, a former light heavyweight champion, returns to the title picture after an impressive 2025 campaign that saw him score back-to-back knockout victories over Jamahal Hill and Khalil Rountree Jr. The Czech veteran, known for his unorthodox striking and ruthless aggression, is attempting to complete a long journey back to the top after vacating his title due to injury and twice coming up short against Pereira in title fights.
On the other side of the Octagon, New Zealander Carlos Ulberg has risen to the forefront of the division. After suffering a setback in his UFC debut, Ulberg has responded with a remarkable nine-fight winning streak, including high-profile victories over former champion Jan Błachowicz and a first-round knockout of Dominick Reyes. The performance-heavy streak has positioned Ulberg as one of the most dangerous contenders in the light heavyweight ranks.
The matchup promises fireworks: both fighters are powerful finishers with a combined history of highlight-reel knockouts and aggressive pace. For Prochazka it is a chance to regain the title he once had; for Ulberg it is a chance to solidify his climb and bring championship gold to New Zealand Kickboxing in the city camp.
UFC 327’s stacked card also includes a flyweight title fight between champion Joshua Van and challenger Tatsuro Taira, among a series of other compelling matchups that round out one of the most anticipated fight nights of 2026.
