When a Brazilian fighter thinks he’s about to headline a UFC show in Europe, you can feel the buzz in the gym and on social media. That was exactly the case for Thiago Santos in late 2017, when he was booked to face Poland’s Michal Materla at UFC Gdańsk on Oct. 28. The clash promised a classic striker‑versus‑ex‑KSW champ storyline, and fans in Gdańsk were already buzzing about a possible knockout festival.
What went wrong with the Gdańsk main event?
Santos rode a two‑fight win streak into the negotiations, dispatching Gerald Meerschaert and Jack Marshman via TKO. Those victories had him looking like a genuine contender in the middleweight ranks, especially after a 2016 loss to Eric Spicely that left a mark on his resume. On the other side of the cage, Materla arrived with a 24‑5 record and a celebrated knockout of UFC vet Rousimar Palhares. His UFC debut had been hyped as a chance to showcase the Polish fighter’s power to a global audience.
However, the drama that unfolded off the canvas proved more decisive than any fight camp. In December 2016, Materla was arrested in Szczecin alongside a group of alleged organized‑crime suspects. While the case never fully derailed his career, the legal cloud made it difficult for the UFC to secure the necessary visas and clearances for a high‑profile debut in Poland.
UFC officials, needing to keep the Gdańsk event intact, pivoted quickly. They replaced the Santos‑Materla headline with a more reliable draw: Donald “Cowboy” Cerrone versus rising welterweight Darren Till. The new headliner promised instant pay‑per‑view numbers, but it also meant Santos lost the spotlight he’d been eyeing.

Santos’ new fight in São Paulo and what it means
Instead of battling for the main‑event limelight in Gdańsk, Santos was reassigned to UFC São Paulo, where he would meet Sweden’s Jack Hermansson. The fight still offered a home‑crowd advantage—Brazilian fans love to rally behind their own—but it was a clear step down on the card hierarchy. Hermansson, a gritty grappler with a solid record, presented a stylistic puzzle that differed from the power‑punching showdown originally scheduled.
From a career‑development perspective, the shift carried several repercussions. First, the exposure gap: a main‑event slot invariably attracts more press, higher viewership, and better sponsor interest. Dropping to a supporting role meant fewer eyes on Santos’ performance, potentially slowing his ascent toward a title shot. Second, the psychological blow—fighters thrive on momentum, and having a marquee opportunity snatched away can dent confidence.
Nonetheless, Santos used the Sao Paulo platform to reaffirm his knockout credentials. He entered the Octagon with his striking arsenal honed, aiming to remind the division that he belongs in the conversation. Even if the bout didn’t carry the same promotional weight, a decisive win could still catapult him back into main‑event contention.
The episode underscores how volatile UFC scheduling can be. Legal issues, visa snags, injuries, or last‑minute promotional decisions can reshuffle entire cards in a matter of weeks. For fighters, adaptability becomes as crucial as skill; navigating these curveballs often defines the long‑term trajectory more than a single win or loss.
While Santos’ Gdańsk dream dissolved, the São Paulo fight offered a chance to rebound, rebuild fan interest, and keep the middleweight division buzzing. The next headline he earns will likely hinge on how convincingly he can finish Hermansson and whether the UFC decides his brand deserves another front‑row slot.
