The 2014 bout featured two featherweight contenders on the rise. It was McGregor's first appearance on a UFC pay-per-view, and the two fought before the co-main event. Fast-forward six years, and he is now the UFC's undisputed biggest draw.
Poirier has undergone a rise of his own. The loss to McGregor sparked a move up to lightweight from featherweight where he is now 10-2 with one no-contest in his last 13 fights.
It's a fight that is sure to draw big pay-per-view numbers and bring plenty of attention to UFC.
Another key lightweight fight is set as the co-main event. Michael Chandler will make his promotional debut against Dan Hooker in a fight that could have title implications.
Here's a look at the complete schedule and the biggest storylines heading into the event.
