Despite never fighting in the UFC, Adriano Moraes is by far the most recognizable name on these prelims. He was a legend of the ONE Championship flyweight division throughout the 2010s and then famously knocked out Demetrious Johnson, arguably the divison’s GOAT, in 2021. Moraes lost to Johnson two subsequent times, and then was knocked out by Yuya Wakamatsu for the vacant ONE flyweight title last March.
He was initially slated to battle the undefeated Muhammad Mokaev, who many consider the best fighter outside of the UFC. However, Mokaev had to be scrapped from the event due to issues obtaining a visa.
