They did big business together at the Ultimate Fighting Championship box office.

Dustin Poirier and Conor McGregor squared off three times between Sept. 27, 2014 and July 10, 2021, as they pushed each other to new heights in the featherweight and lightweight divisions. Poirier emerged victorious in two of the three meetings, proving his star could shine just as brightly as the braggadocios Irishman’s when it mattered most. Now more than two years removed from what figures to be their final clash, the two men remain interminably linked by what took place between them inside the cage.
