Fighter on Fighter: Breaking down UFC 257’s Dustin Poirier Share this story Veteran knockout artist, Dustin Poirier, will rematch former double champ, Conor McGregor, this Saturday (Jan. 23, 2021) at UFC 257 on “Fight Island” in Abu Dhabi. It’s been a bit more than six years since McGregor pretty effortlessly walked through Poirier on his rise to the Featherweight crown. For Poirier, this was his fourth loss in high-profile Featherweight fights, four defeats that could have instead lead to title opportunities. He shifted to Lightweight immediately after the defeat. Lightweight helped alleviate some of Poirier’s woes, seemingly bolstering both his durability and punching power. However, it was the improvement to his boxing and footwork that allowed Poirier to fully make the transition from scrappy Top 10’er to genuine title threat. Poirier’s streak from 2017-2019 that saw him capture the interim belt is a genuinely amazing accomplishment, a reward for his decade of dedication.
