USADA to end partnership with UFC in 2024 after Conor McGregor officially re-enters testing pool - ‘Relationship became untenable’

The drugs don’t work?

United States Anti-Doping Agency (USADA) era in Ultimate Fighting Championship (UFC) is officially coming to an end.

Mixed martial arts (MMA) fans have been anticipating the return of former UFC Featherweight (and Lightweight) champion, Conor McGregor, for essentially all of 2023 after he was paired with Michael Chandler as coaches on The Ultimate Fighter (TUF) 31. However, “The Notorious” has been ineligible to compete because he’s been out of USADA’s testing pool, requiring athletes to submit six months of testing before they can compete.

Well, most of them.

McGregor officially re-entered the pool this past weekend, according to USADA CEO, Travis Tygart. Ultimately, he may not have to undergo six months of testing after all as USADA additionally noted that the UFC partnership will end at the start of the new year.

We can confirm that Conor McGregor has re-entered the USADA testing pool as of Sunday, October 8, 2023. We have been clear and firm with the UFC that there should be no exception given by the UFC for McGregor to fight until he has returned two negative tests and been in the pool for at least six months. The rules also allow USADA to keep someone in the testing pool longer before competing based on their declarations upon entry in the pool and testing results.

Unfortunately, we do not currently know whether the UFC will ultimately honor the six-month or longer requirement because, as of January 1, 2024, USADA will no longer be involved with the UFC Anti-Doping Program. Despite a positive and productive meeting about a contract renewal in May 2023, the UFC did an about-face and informed USADA on Monday, October 9, that it was going in a different direction.

We are disappointed for UFC athletes, who are independent contractors who rely on our independent, gold-standard global program to protect their rights to a clean, safe, and fair Octagon. The UFC’s move imperils the immense progress made within the sport under USADA’s leadership.

The relationship between USADA and UFC became untenable given the statements made by UFC leaders and others questioning USADA’s principled stance that McGregor not be allowed to fight without being in the testing pool for at least six months. One UFC commentator echoed this, recently declaring that USADA should not oversee the UFC program since we held firm to the six-month rule involving McGregor, and since we do not allow fighters without an approved medical basis to use performance-enhancing drugs like experimental, unapproved peptides or testosterone for healing or injuries simply to get back in the Octagon.

Fighters’ long-term health and safety —­ in addition to a fair and level playing field — are more important to USADA than short-term profits at the expense of clean athletes. USADA is proud of the work we’ve done over the past eight years to clean up the UFC, and we will continue to provide our unparalleled service to UFC athletes through the remainder of our current contract, which ends December 31, 2023. As always, we will continue to uphold the rights and voices of clean athletes in all sport.

McGregor hasn’t fought since his trilogy bout against Dustin Poirier, which he lost via first round technical knockout (watch highlights) at UFC 264 in July 2021. The Irishman suffered a nasty broken leg in the bout (see it), resulting in his extended time away from the sport.

It’s been a USADA nightmare ever since.
