Carlos “Black Jag” Ulberg is officially on the doorstep of greatness, stepping into the main event of UFC 327 this Saturday to battle Jiri Prochazka for the vacant light heavyweight championship. It’s a title fight that represents the culmination of an incredible journey for the 35-year-old, but long before the bright lights of the Octagon, his destiny was written in his Samoan bloodline.
“The Ulbergs, they were known in Samoa for being the fighters,” Ulberg once noted, realizing from a very young age that combat was a family tradition he was meant to continue. Growing up in Ōtara, New Zealand, his Samoan roots were the undeniable bedrock of his identity and discipline. He was raised partly by strict Samoan Aunties who instilled a deep sense of respect in him, while his father—a boxer who proudly represented Samoa at the Commonwealth Games—forged his physical toughness. His father’s approach to parenting was steeped in combat; he taught a young Carlos how to read and spell by enforcing boxing drills and push-ups for every incorrect word. Though he spent time navigating various foster families and boys’ homes in New Zealand—which gave him a broad perspective on how quickly life can change—it was that fierce Samoan fighting spirit that always anchored him.
That warrior lineage translates directly into his terrifying presence in the cage. After pivoting from a promising rugby league career in New Zealand—one that almost landed him with the Warriors before an on-field brawl led to a six-week ban—Ulberg focused his immense physical gifts entirely on striking. Today, he brings a terrifying nine-fight win streak into this championship clash, a run built almost entirely on his devastating knockout power. His City Kickboxing teammate, former UFC middleweight champion Israel Adesanya, has praised Ulberg’s incredible force, noting that his shots “would have dropped most light-heavyweights, most heavyweights”. Ulberg showcased this destructive capability with a stunning first-round knockout over Dominick Reyes, proving his elite tools can put anyone to sleep.
At UFC 327, Ulberg faces a uniquely terrifying puzzle in Jiri Prochazka. Prochazka is famous for his unpredictable “weaponized chaos,” a dangerous style that completely overwhelms opponents. Ulberg has immense respect for Prochazka, calling him a “likable guy,” but he knows that styles make fights, and victory goes to whoever finds their flow first. For Ulberg to walk away with the belt, his clearest path to victory lies in dictating the tempo and forcing a highly technical kickboxing match. Top MMA coaches suggest that Ulberg must rely on his pristine fundamentals: keeping his hands up, his chin down, and using his jab and long kicks to manage the distance. If he can slow the fight down into a strategic chess match and avoid getting sucked into Prochazka’s wild, frenetic exchanges, his efficient, counter-striking game will shine. Ulberg has the speed and clean shot selection to capitalize whenever the chaotic Prochazka inevitably finds himself out of position.
Securing the light heavyweight crown would be a monumental achievement, not just for Ulberg, but for New Zealand and the renowned City Kickboxing team. Becoming another UFC champion from New Zealand would permanently cement his legacy as a hometown hero, but more importantly, it would be the ultimate tribute to his Samoan heritage. He purposely built his local profile by fighting in New Zealand early in his career to ensure his hometown knew who he was. While he admits he is slightly bummed he won’t be fighting the legendary Alex Pereira for the belt, capturing this vacant title is his ultimate professional goal. Now, the kid from Ōtara who proudly carries the fighting legacy of the Samoan Ulbergs has the chance to rule the light heavyweight division. If his clean technique and raw power find their mark this Saturday, Carlos Ulberg will return to Aotearoa as an undisputed world champion, proving that the fighting spirit of his ancestors is alive and well on the world’s biggest stage.
