After splitting two fights over the course of seven years, Dustin Poirier and Conor McGregor put an end to their rivalry in the main event of UFC 264 on Saturday.
McGregor won the first fight by knockout at UFC 178 in 2014, when the two were featherweights.
Poirier and McGregor both lost to Khabib Nurmagomedov and then crossed paths again at UFC 257 in January. This time, Poirier secured the win with a second-round knockout.
On Saturday night, the tie was broken in crazy fashion after McGregor broke his ankle.
On top of the bad blood, UFC president Dana White previously said the winner would fight for the UFC lightweight title next against champion Charles Oliveira.
