Fallon Fox, the first openly transgender MMA fighter, took to Twitter yesterday to explain that she “enjoyed” fracturing the skull of one of the first woman to fight her, and that she loves, “smacking up TERFs  in the cage…it’s bliss!” 

Fallon, who was previously a member of the US military, came out as transgender in 2013 after winning her first two fights as a female. Her coming out sparked a deep debate in the MMA community, with many commentators saying that they could not support a biological male competing in the female division because, amongst other reasons, her greater bone density would lead to an increased risk of injuries. Others, however, said that Fallon had every right to fight as a woman and that those opposed to her were transphobic. 

One MMA fighter, Matt Mitrione, was suspended from the UFC for calling Fox a “lying, sick, sociopathic, disgusting freak.” 

Fox is most famous for her fight against Tamikka Brents, which took place shortly after Fox came out as transgender. During the bout Brents suffered a concussion and her orbital bone fractured after a strike from Fox – she needed seven staples in her skull after the fight. Fallon won the fight by TKO, but retired from MMA afterwards. 

After the fight Brents spoke about the experience, saying “I have struggled with many women and I have never felt the strength I felt in a fight like that night. I can’t answer whether it’s because she was born a man or not because I’m not a doctor. I can only say that I have never felt so dominated in my life and that I am an abnormally strong woman in my own right.” 

The second fight Fox is referring to in her tweet was against Ericka Newsome, which took place before Fox was known to be transgender. Fox ended that fight with a knee to Newsome’s head which knocked Newsome out. 

Before retiring from MMA Fallon’s record was 5-1-0 (Win-Loss-Draw)
