As of today, March 26, UFC legend Conor McGregor is retired from the fight game.

Despite his own recent remarks about completing the trilogy with Nate Diaz and a rematch with Khabib Nurmagomedov, McGregor took to twitter early Tuesday morning to announce, "I've decided to retire from the sport formally known as Mixed Martial Arts."

McGregor, 30, sent out a similar "retirement" tweet in April of 2016, but he was back in the octagon just months later for his highly anticipated rematch against Nate Diaz. There's hope that he'll pull a similar stunt this summer and return to UFC for at least one more fight against Diaz, but for now, he is a retired man.

In honor of The Notorious' illustrious run in the UFC, we take a look back at some of the most memorable, defining moments of his career.
