Dustin Poirier is already getting itchy knuckles just months after his official UFC retirement. Earlier this year at UFC 318, former UFC interim lightweight champion Dustin Poirier made his final walk to the Octagon when he took on Max Holloway for the BMF title in the promotion’s return to Louisiana. Should Dustin Poirier return for a boxing fight? Over the last few years, it has become a trend for retired UFC fighters to make their comebacks to combat sports by fighting in the boxing ring. Throughout his time in the UFC, Poirier was considered to be a strong boxer, and his skills could likely transfer over to the boxing ring.
