Much luv to him and @BrendanAllenMMA for reppin Louisiana right!! #ufcvegas4!— Lil Wayne WEEZY F (@LilTunechi) June 28, 2020What's next for Dustin Poirier?Heading into this fight, Dustin Poirier suffered a loss to Khabib Nurmagomedov. However, 'The Diamond' got back to winning ways in the best possible way one could've imagined, putting together an all-time classic with Dan 'The Hangman' Hooker.Nevertheless, it remains to be seen what's next for Dustin Poirier and while he will be spending some quality time with his family and recovering from this savage bout, fans would definitely love to see 'The Diamond' back in action before the year. The man himself also claimed that he could possibly fight one more time in 2020 or 2021 itself.A fight against former interim Lightweight Champion, Tony Ferguson could be on the cards but Poirier could get his rightful shot at the Undisputed UFC Lightweight Champion of the world, after Khabib Nurmagomedov and Justin Gaethje settle their rivalry over the World Title.
