Conor McGregor gets tested by USADA on yacht, not officially retired

Conor McGregor is still saying he's retired, but he apparently hasn't filed the paperwork yet with the U.S. Anti-Doping Agency (USADA) that would actually signify his official exit from mixed martial arts.

McGregor, the former UFC two-division champion who hasn't fought since defeating Donald Cerrone at UFC 246 in January, tweeted on Friday that USADA showed up to his yacht to collect a sample. Since McGregor is in the testing pool, he is required to share his whereabouts with USADA via an app on his smartphone. He posted two photos in the tweet, one of the letter sent from USADA, the other of a testing kit.

"What's going on here @ufc ? USADA have just arrived to my yacht this morning for testing? I've retired guys! But go on then, I'll allow them test me. It's all natural here baby! Forever and always, God Bless 180km across the Mediterranean Sea tomorrow! LET'S GO!!"

McGregor followed up that tweet by taking a shot at Nate Diaz. A trilogy fight with Diaz is one of the fights that McGregor has often spoke about on social media.

Moments after the conclusion of UFC 250 in June, McGregor tweeted that he was retiring from the sport and told ESPN's Ariel Helwani that "the game just does not excite me." It was not the first time McGregor has tweeted a retirement message. He first retired in March 2016, but then returned later that summer and defeated Diaz that August. McGregor also retired via Twitter in April 2019, yet returned to face Cerrone earlier this year.

McGregor was on his yacht ahead of his participation in the Marathon Endurance Race, a 180-kilometer charity voyage that will have McGregor racing on a water bike from Corsica to Monaco.
