The UFC is set to make its 16th return to London this weekend with UFC Fight Night 255 on March 22, 2025, marking its comeback to the O2 Arena after more than a year. This time, the event boasts an even stronger lineup than its 2023 edition. At the forefront of the action, Leon Edwards takes on Sean Brady in a highly anticipated welterweight clash. For the former champ, this fight is more than just a matchup—it’s a chance to re-enter title talks after losing his crown to Belal Muhammad last year.
But Edwards isn’t the only one seeking to pave his way to gold. The co-main event sees former light heavyweight champion Jan Błachowicz return to the Octagon after a disappointing 2023 loss to Alex Pereira. Now, he faces fast-rising star Carlos Ulberg in a showdown that pits veteran experience against youthful momentum. This isn’t just a fight—it’s a battle of generations. Will the Pole prove that experience prevails, or will the Kiwi establish himself as the division’s next big thing?
With that in mind, we’ve broken down the UFC London co-main event and put together some bold predictions. So, let’s get straight to it.
UFC London: Jan Blachowicz vs. Carlos Ulberg stats
Jan Błachowicz, a seasoned veteran who turned 42 last month, has spent nearly two decades in the MMA world, staying loyal to just two promotions throughout his career. He began his journey with KSW—Poland’s premier MMA organization—where he became the light heavyweight champion before entering the UFC. As he prepares for UFC London, the Pole carries an extensive resume, boasting 40 professional MMA fights.
However, his experience extends beyond the cage, as he also holds an undefeated 34-0 record in Muay Thai. Despite now being 42 years old, he remains a top-three contender in the light heavyweight division, with signature wins over elite fighters like Israel Adesanya and Dominick Reyes, and Luke Rockhold. Yet, his recent performances have been a mixed bag. Whether due to age or form, Jan Blachowicz has struggled to maintain consistency, securing just two wins in his last five outings, with two losses and a draw in that span.
Opposing him at UFC London is the surging Carlos Ulberg, currently ranked #6 in the division. The event marks his ninth UFC appearance, and he arrives on a dominant seven-fight win streak. A former kickboxing standout, ‘Black Jag’ amassed a 19-2 record across regional and international circuits before transitioning to MMA in 2019.
His success earned him a spot on DWCS in November 2020, just days after his birthday, where he made an instant impact with a knockout victory. Since then, Carlos Ulberg has built a reputation as a dangerous finisher, with most of his wins coming by knockout. His most recent triumph, a unanimous decision over Volkan Oezdemir in late 2024, cemented his place as a rising force in the division. Now, with a shot at the #3-ranked Jan Blachowicz, a victory at UFC London could be his ticket to a long-awaited title opportunity.
Blachowicz vs. Ulberg breakdown and prediction
Carlos Ulberg is in the best form of his career right now, especially when compared to Jan Blachowicz’s recent struggles and time on the sidelines since mid-2023. However, it’s impossible to overlook the legacy the Pole has built as a true mixed martial artist since 2008. Known for his dangerous shin kicks, the former champ isn’t just a dangerous striker—he also possesses some of the best wrestling in the light heavyweight division. A perfect example is his battle with Alex Pereira at UFC 291, where he utilized his wrestling for all three rounds.
The Kiwian, much like Pereira, is a skilled kickboxer with exceptionally striking power. He’s earned a reputation for his knockout ability when he slept Alonzo Menifield in just 12 seconds. However, his most notable submission came in 2023 when he defeated Da Woon. What sets Carlos Ulberg apart is his knack for finishing fights quickly, which has helped him rise rapidly in the light heavyweight division. The key question, however, is whether his endurance will be enough to withstand the seasoned like Jan Blachowicz. The Pole’s endurance is one of his defining traits, with a ‘gas tank’ that allows him to push through all five rounds, even in the later stages of a fight.
But, with age and his recent form in question, many are wondering if he can maintain that level against a younger, hungry challenger. That’s why, in the upcoming UFC London event, Jan Blachowicz enters as the underdog, with Ulberg being the clear fan favorite. When breaking down both fighters’ strengths and styles, the key to Ulberg’s victory lies in his ability to finish Blachowicz early.
If he can’t, however, the seasoned veteran’s experience and durability could pose significant problems for the up-and-coming light heavyweight contender. With UFC Fight Night 255 set to take place this weekend on March 22, all eyes are now on the event. Who do you think will emerge victorious? Share your prediction below!
