McGregor, whose last fight against Poirier was on 11, July 2021, ended in just the first round as the Irishman suffered a severe leg injury.
The video, captioned “The shots nightmares are made of”, was posted on his @TheNotoriousMMA Twitter account and has already amassed 300,000 views after just five hours.
The fight against Poirier was the final in a trilogy of fights, with McGregor winning their first bout and the American walking away with the final two.
The defeats mean that McGregor has lost three of his last four fights, with the other loss coming at UFC 229, after his highly anticipated lightweight title fight against Khabib Nurmagomedov.
McGregor is expected to make his return towards the later stages of 2022 following comments made by president of the UFC Dana White.
White said: “He’s not back until the fall, if everything goes right. A lot of the matchups will play out this summer and whoever wins or loses, when Conor is cleared by a doctor and ready to go, we’ll figure out who’s next.”
If McGregor does make a return to UFC, then it’s expected that he could target the top dog, the current lightweight champion Charles Oliveira.
Oliveira has been champion since May 2021, following a title fight against Michael Chandler.
However, McGregor may be looking to secure his wealth, with an offer from YouTuber Jake Paul still on the cards.
Paul, 25, offered the UFC superstar $50 million for a boxing match back in December 2020.
He accused the Irishman of being scared to fight him, saying: “You’re ducking me because you don’t want to lose to a f****** YouTuber.”
Paul is pushing for the fight, with the American social media personality offering just last month to lose 15lbs to try and secure the potential ground-breaking fight.
