In 2013, Fallon Fox became the first transgender fighter to compete in professional mixed martial arts. At the time, this idea was met by criticisms from many within the community, most notably from UFC analyst Joe Rogan.
Five years later, Fox is once again in the crosshairs of fighters. The most recent one who put her on blast is Paulo Henrique Costa, who actually issued a challenge for a fight through a Facebook video (translation via AG Fight and Lucas Rezende).
“I would love it if this Fallon Fox fought a man,” Costa said.
