Irish martial arts star Conor McGregor announced his retirement from the age of 31, according to what he confirmed on his official Twitter account today, Sunday. “I decided to retire fighting, thank you for all the wonderful memories, what a journey,” said the lightweight and featherweight world champion in the UFC category (Extreme Fighting Championship), and attached the tweet to a picture of him and his mother Margaret during a celebration of a victory in Las Vegas.

McGregor is considered one of the most famous athletes in the world, especially in combat sports, and he faced veteran American boxer, Floyd Mayweather, in 2017 and lost to him in the tenth round.

The fighter, who had 22 wins and 4 defeats in his career, retired in 2019 after losing to Russian Khabib Nurmagomedov in late 2018, but he returned from that last January on the day he defeated the American Donald Crony with a technical knockout in just 40 seconds.
