Navajo Stirling knocks out Jan Błachowicz in Belgrade and opens the door to fights with the UFC elite
Navajo Stirling recorded the biggest victory of his career to date by defeating former champion Jan Błachowicz via technical knockout in the co-main event of UFC Fight Night: Medić vs. Rodriguez, held on August 1, 2026, at Belgrade Arena. The undefeated New Zealander finished the Polish veteran after two minutes and 56 seconds of the first round, first with a powerful right hand that sent him to the canvas and then with a series of strikes from the top position. Referee Marc Goddard stopped the fight after Błachowicz was no longer able to respond effectively to the attack. The official result was recorded as a technical-knockout victory, while Stirling's professional record improved to 11 wins without a loss. In a single evening, the 28-year-old fighter from New Zealand's City Kickboxing team made the transition from a promising name to a serious candidate for a place among the leading contenders in the light heavyweight division.
The outcome carried additional weight because Stirling accepted the fight less than three weeks before the event. Błachowicz was originally scheduled to face Bogdan Guskov again, but the Uzbek was redirected to the main event in Abu Dhabi against Magomed Ankalaev. According to the UFC's announcement ahead of the Belgrade event, Stirling immediately offered to step in as a replacement, even though this represented the biggest leap in opponent quality of his short career. Until then, he had built his undefeated streak gradually, but he had never stood opposite a fighter with experience of winning and defending the UFC belt. The victory over Błachowicz is therefore not merely another result in the sequence, but confirmation that Stirling's speed, precision and composure can also be transferred to contests against elite, highly experienced opponents.
Turned an early problem into a finish in less than three minutes
The beginning of the fight was not entirely one-sided. According to MMA Fighting's report, Błachowicz moved forward early, took advantage of one Stirling slip and attempted to impose physical contact against the fence. The Pole then briefly dropped the New Zealander to one knee with a clean left hand, and Stirling was bleeding from the nose after that attack. Instead of reacting in panic, he quickly tied up in the clinch, gained several seconds to recover and re-established his preferred distance. That moment proved crucial because Błachowicz, encouraged by his early success, continued to apply pressure, but in doing so left room for a counterattack.
Stirling found the answer with a precise right hand that struck Błachowicz in the head and completely changed the course of the bout. The former champion lost his balance and fell, and the New Zealander did not allow him time to recover defensively. Punches and elbows on the ground followed, including attacks that opened a cut on Błachowicz's face. Goddard judged that the Pole was no longer defending himself sufficiently and stopped the contest at 2:56 of the first round. The speed of the finish was particularly impressive because, throughout his long career, Błachowicz had been known for his ability to slow fights down, his tactical discipline and his physical toughness against the world's best light heavyweights.
In the brief appearance, Stirling demonstrated several qualities that often prove more important in the strongest competition than knockout power alone. He survived an uncomfortable start without abandoning his plan, did not unnecessarily engage in an exchange after being hit and recognized the moment when the line for his right hand opened. After the knockdown, he did not rush into a disorderly attack, but maintained positional control and selected his strikes until the referee intervened. That combination of composure and finishing instinct was the main message of his victory. His opponent was not a fighter lacking experience, but a 43-year-old veteran with more than two decades of professional appearances and a long tenure in the UFC.
From gradual development to six UFC victories
Stirling earned a UFC contract in September 2024 by knocking out Phillip Latu in the second round of Dana White's Contender Series. The organization's official profile shows that he earned his first three UFC victories by judges' decisions against Tuco Tokkos, Ivan Erslan and Rodolfo Bellato. Such a start did not merely improve his record, but also gave him time in the Octagon against different styles. During 2026, he began finishing opponents: he stopped Bruno Lopes with strikes in the second round in March and Ion Cuțelaba in the same manner in June. Only six weeks later, he accepted the bout with Błachowicz and added the most important result of his career.
He now holds a 6-0 record in official UFC appearances, in addition to the Contender Series victory that opened the organization's doors to him. He has finished his last three opponents by stoppage, demonstrating a development from a technically secure round-winner into a fighter capable of exploiting even the smallest mistake. At the same time, he preserved his professional unbeaten record of 11-0, a rare distinction in the division up to 93 kilograms, where one clean strike often erases a previous tactical advantage. Błachowicz was the first opponent to provide Stirling with a direct test against a former champion and ranked veteran. The answer arrived before the third minute had expired.
His development is tied to City Kickboxing, the Auckland gym that has produced several world-class fighters in recent years. Stirling trains there with current light heavyweight champion Carlos Ulberg, which means his rise cannot be viewed separately from the unusual situation at the top of the division. In an interview published before the fight, he said that he did not want to face Ulberg or Robert Whittaker, who also trains with the same group and competes in the division up to 93 kilograms. Sherdog reported his message that, as a younger member of the team, he does not feel the need to rush toward an internal showdown, but instead wants to help Ulberg consolidate the title. Such a stance could become important if Stirling rapidly approaches a title fight after his victory in Belgrade.
Callouts of Rountree and Costa clearly show his ambition
After the stoppage, Stirling expressed respect for Błachowicz, calling the opportunity to compete against the former champion an honor and emphasizing that he had followed his career for a long time. He also praised his coaches and said he had remained faithful to the agreed game plan. He then turned his attention toward the next step and publicly called out Khalil Rountree Jr. and Paulo Costa. In doing so, he showed that after the biggest victory of his career he is not looking for an easier transitional bout, but another matchup with a recognizable name and an opponent who would keep him at the center of the conversation about the top of the division.
Rountree is an established light heavyweight with pronounced striking power, so such a bout would offer Stirling another test against a dangerous fighter from the upper section of the rankings. Costa gained wider recognition in the middleweight division, but his name and physical style make him an attractive potential opponent in the higher division. As of August 2, 2026, neither of those bouts had been officially arranged, and the schedule at the top of the division will depend on decisions by the UFC's matchmakers and other already planned fights. Nevertheless, the public callout was not accidental: both names offer Stirling visibility, sporting risk and the possibility of rapid advancement. After Błachowicz, it will no longer be easy to present him as a fighter who still needs to prove himself against elite competition.
Reactions from other professionals further emphasized the change in his status. MMA Fighting reported former welterweight champion Belal Muhammad's assessment that Stirling had established himself as a genuine contender with this victory. Such reactions do not determine the rankings or guarantee a title fight by themselves, but they show how the performance was perceived within the fighting community. It is particularly important that Stirling did not win a close decision in a tactically closed bout, but finished a former champion in the first round. In a division where the path toward the belt often changes after one powerful result, the manner of victory can be almost as important as the name of the defeated opponent.
Błachowicz without a victory since 2022
For Jan Błachowicz, the defeat in Belgrade extended his winless period to five consecutive appearances. Ahead of the fight, MMA Fighting stated that the Pole last won in May 2022, when Aleksandar Rakić was forced to withdraw in the third round because of a knee injury. Since then, Błachowicz has recorded two draws and now three defeats, while the result against Stirling lowered his professional record to 29 wins, 12 defeats and two draws. Although most of his recent appearances were against highly ranked opponents, the winless streak and the fact that he is 43 years old inevitably raise the question of his next move. Immediately after the event, Błachowicz did not officially confirm a decision about continuing his career.
His position should be viewed in the context of a career that has already left a significant mark on the light heavyweight division. Błachowicz won the vacant UFC title in 2020 by technical knockout against Dominick Reyes, and then defended it in 2021 by unanimous decision against the then-undefeated UFC middleweight champion Israel Adesanya. He lost the belt to Glover Teixeira, but even afterward remained involved in fights that directly influenced the rankings near the top. His experience, power and versatility made him an important benchmark for new generations of light heavyweights. That is precisely why Stirling's victory carries more weight than an ordinary statistical improvement.
The defeat in Belgrade nevertheless differs from the close judges' decisions and draws that marked the previous years. Błachowicz started the fight well and landed the first serious strike, but was then stopped in an exchange in which the younger opponent displayed a quicker reaction and a more effective finish. It will now be important for the UFC to assess what type of bout it can offer him, provided the Pole decides to continue. A return against another young striker would carry great risk, while a meeting with a veteran of similar experience could offer a more balanced context. There is currently no confirmed information about his next appearance.
Belgrade event produced a historic evening of stoppages
Stirling's victory was part of the first UFC event held in Serbia. The event at Belgrade Arena was headlined by Uroš Medić and Daniel Rodriguez, and Medić won the main event by technical knockout after only 30 seconds. According to the UFC's official results and MMA Fighting's complete list, as many as 12 of the 14 fights ended by stoppage, while ten were concluded in the first round. Only the bouts between Aleksandar Rakić and Marcin Tybura and between Borislav Nikolić and Mark Vologdin reached the judges' decision. Media reports after the event stated that this set a new modern-era UFC record for the number of first-round finishes at a single event.
In such an environment and among a series of rapid finishes, Stirling's performance nevertheless stood out because of the quality of his opponent. At the same event, domestic and regional fighters received a major international stage, while Belgrade hosted the world's largest MMA organization for the first time. For the UFC, the event represented a continuation of its expansion into European markets, while for the fighters on the card it was an opportunity to perform before an audience that rarely has access to an event of that level. Stirling turned that opportunity into a result that will directly affect his position in the division. Although the official rankings update still has to show the extent of his rise, a victory over a former champion and previously highly ranked Błachowicz almost certainly leads him toward a significantly more demanding next opponent.
The biggest unknown now is not whether Stirling belongs to the broader circle of contenders, but how quickly the UFC wants to test his ceiling. He has six victories in the organization, three consecutive stoppages and a result against an opponent whose name carries international weight. At the same time, the title is held by his gym teammate Ulberg, while Stirling publicly rejects the possibility of them fighting each other. Because of that, his path could be directed toward major bouts without an immediate title challenge, at least until the balance of power at the top changes. Rountree and Costa fit such a strategy, but the UFC has not yet announced whom the undefeated New Zealander will face next in the Octagon.
The victory in Belgrade remains a turning point regardless of the future schedule. Stirling accepted the biggest challenge of his career on short notice, overcame the first serious problem in the fight and finished a former champion before the end of the first round. In doing so, he confirmed that his place among the prominent names in the light heavyweight division is no longer merely a projection based on potential. His next appearance will show whether he can maintain the same pace against another world-class opponent, but after August 1, 2026, the question is no longer whether he will receive such an opportunity, but against whom he will receive it.
