That face belongs to UFC heavyweight fighter, Ben Rothwell.
Rothwell actively sought and received an exemption from the state of Wisconsin to use the controversial therapy in advance of his UFC 164 bout against Brandon Vera.
Former UFC heavyweight champion, Frank Mir, who is a previous user, also received the same exemption.
UFC 164 takes place a week from Saturday at the Bradley Center in Milwaukee. The pay-per-view event featured a lightweight title fight between Benson Henderson and Anthony Pettis in the main event.Tags: Ben Rothwell, Brandon Vera, frank mir, mma, MMA NEWS, ufc, ufc news
