Some of the biggest names in the sport help define Poirier's legacy ahead of his UFC 318 retirement fight vs. Max Holloway

As a part of the tribute to "The Diamond," the promotion put together an incredible video titled "Paid In Full: The Dustin Poirier Story," which first played during the UFC 318 broadcast before his final fight against Max Holloway.

Dustin Poirier will receive a hero's welcome in his native Louisiana at UFC 318 when he battles Max Holloway for a third time in their careers. It's a respect Poirier earned from his peers and the promotion that they would take a PPV event to New Orleans for the first time in 25 years as a proper send off to one of the good guys in the sport's history.
