UPPRCUT MMA on Instagram: "Dustin Poirier may not have held the undisputed belt for long, but he’s fought and beaten some of the best to ever do it. Wars with champions, knockouts over legends, and never backing down from anyone. Win or lose, he shows up every time and leaves everything in the cage. Some fighters wear gold… others earn respect. The Diamond is the uncrowned king. #ufc #dustinpoirier"
