Matt Mitrione was talking about Fallon Fox, a transgender mixed-martial artist.
Mitrione called Fox a "lying, sick, sociopathic, disgusting freak" during an interview on the MMA Hour show.
“The UFC was appalled by the transphobic comments made by heavyweight Matt Mitrione today in an interview on the ‘MMA Hour.’
“The organization finds Mr. Mitrione’s comments offensive and wholly unacceptable and -- as a direct result of this significant breach of the UFC’s code of conduct -- Mr. Mitrione’s UFC contract has been suspended and the incident is being investigated.
“The UFC is a friend and ally of the LGBT community and expects and requires all 450 of its athletes to treat others with dignity and respect.”
