When Jorge Masvidal hit the other guy, he had interrupted Masvidal during Masvidal's interview, they said 'bla bla bla' and then the Leon Edwards guy said "shut up", or "shit up", and then Masvidal walked over to hit him (mind you first with his hands behind his back as if he just wanted to talk and then threw punches - a video had popped up on my youtube recently with Masvidal and Romero on a Cuban TV show where Masvidal half jokingly explains that if you wanna win a streetfight, best walk up, but smiling so the other guy expects nothing and then give a headbutt...)
