Katlyn Cerminara VS Mackenzie Stiller

Katlyn Cerminara stopped Mackenzie Stiller by TKO at 4:46 of the opening round in a women's flyweight contest at UFC Fight Night: Buckley vs. Malott in Edmonton on October 17, 2026. Stiller was the aggressor from the outset, pressing forward and mixing in spinning attacks, but Cerminara answered with patient counter-punching and stifled a takedown attempt early in the round. Stiller landed a head kick midway through that Cerminara absorbed without breaking stride, continuing to work behind her jab and counters. The finish came when a Cerminara shot visibly hurt Stiller, who struggled to defend a follow-up flurry of punches, and the referee stepped in to stop the contest. The stoppage marked Cerminara's first TKO win in a decade and handed Stiller her first career loss in what was her UFC debut.

Katlyn Cerminara and Mackenzie Stiller bring women's flyweight action to the Rogers Place prelim card, competing in a division that remains fiercely competitive in the UFC's stacked 125-pound roster. Both fighters know the division's tight talent margin means the difference between staying on the active roster and being cut can come down to one compelling performance — or one misstep.
