In a TMZ interview, UFC women's champ Ronda Rousey said transgender fighter Fallon Fox has an "unfair advantage" because of being born a man. However, Rousey says she is not scared of Fox because she can "knock out anyone in the world."

Last year, Fox admitted to being transgendered and a slew of controversy erupted over whether or not fighting in the women's division is fair. Recently, Fox TKO'd Tamikka Brents, who suffered a concussion and a broken orbital bone during the fight which required seven staples in her head, according to CagePotato.com. Brents said that she had never felt that kind of strength in a fighter before, and felt "overpowered" by Fox's strong grip.

Rousey responded to Brents's allegations in the TMZ interview saying Fox does have an "unfair advantage" because of going through puberty as a man. "There's no undo button on that," Rousey said. However, Rousey confidently said that she isn't scared: "I can knock out anyone in the world."

The president of the UFC has also declared an unfair advantage saying, "Bone structure is different, hands are bigger, jaw is bigger, everything is bigger. I don't believe in it."

Fox went on the defensive Saturday on Facebook saying:

I'm quite sure that there are quite a few female MMA fighters who have the guts to fight another skilled woman without peeing their panties.

They may throw all kinds of backwards, bogus bone density or bone structure arguments in it to possibly save face if they lose — because they sense that people are ignorant on bones within sport.
