Mixed martial arts (MMA) fighter Fallon Fox opens up about being transgender in a new interview with Outsports' Cyd Zeigler, but admits she has some long-standing reservations about coming forward. "For years I've known at some point it's very likely the shoe would drop," Fox is quoted in the interview as saying. "Maybe someone would guess that I'm trans. Maybe they would know me from my life before I transitioned. I've been waiting for that phone call to happen. And Saturday night, it happened."
