McGregor was extremely confident of beating Poirier for a second, ahead of their meeting on Saturday night, using his 'Mystic Mac' powers to claim a first round stoppage.
Even Khabib Nurmagomedov backed the idea that the Irishman might win early, however Poirier had other plans on Saturday night.
The Diamond ended the fight in the second round, handing McGregor his first knockout loss, with some great striking.
Whilst the strikes saw the referee wave it off, it was Poirier's calf kicks that really did the damage to set up the opening for the American.
A slow-mo video shows the moment that the kicks really took their toll as McGregor's leg buckled without a kick landing. The Irishman simply moves his leg to launch an attack and the damage from the kicks is obvious.
McGregor had looked good in the first round, and was actually ahead on all three of the judges cards, landing the better shots and even defending well against his opponent's takedown.
The Irishman also landed punches in the second round but the kicks from Poirier kept landing over and over, barely being checked by his opponent.
It took just 15 more seconds from the moment McGregor's leg buckled for the ref to call the fight, with former interim lightweight champ Poirier felling his opponent and continuing to rain down punches afterwards.
There was no doubt after the fight that the kicks really did have an effect on McGregor, as he videoed backstage after the fight needing a crutch to help him walk.
In a meeting with his rival, McGregor jokingly said 'you broke my leg, you b*stard,' but it looks like the insult was the only part that was a joke.
There was incredible respect shown between the two men ahead of the fight, somewhat surprising for McGregor, and that continued after wards.
There was little in the way of excuses for the Irishman and instead he just praised the victor and said they would do it again, with the score now 1-1.
