In the world of mixed martial arts, the partnership between the UFC and the U.S. Anti-Doping Agency (USADA) has been a cornerstone of ensuring a clean and fair sport. However, recent developments surrounding UFC fighter Conor McGregor have triggered a significant split between the two organizations, marking a new chapter in the sport’s drug-testing landscape.


On October 12th, 2023, USADA made a critical announcement: Conor McGregor had officially returned to the drug-testing pool, signaling a potential comeback fight. But this news came with a twist. CEO Travis Tygart’s statement in an accompanying release revealed that the partnership between USADA and the UFC would cease to exist, effective January 1, 2024.

The root of the discord between the two parties can be traced back to McGregor, the UFC’s most prominent star. McGregor had previously left the testing pool after suffering a fractured leg during a fight against Dustin Poirier in July 2021. According to the UFC’s anti-doping policy, maintained by USADA, any fighter re-entering the drug-testing pool must undergo a mandatory six-month period of testing and pass two drug tests before they can compete again.

However, it’s essential to note that there was an exception to this rule. The UFC retained the authority to waive the six-month waiting period if they deemed it unfair to the fighter, but the two successful drug tests were still a requirement.


USADA’s decision to end the partnership stems from what they described as an “untenable” situation involving McGregor. The controversy escalated when UFC president Dana White hinted in a July interview with TSN that McGregor might return to the octagon before the end of the year, effectively bypassing the six-month testing requirement.


Dana White’s comments, along with other statements from UFC leadership, provoked a reaction from USADA. They questioned the principles of USADA’s anti-doping stance, eventually leading to the dissolution of the partnership. In the wake of this split, White referred to USADA’s move as a “scumbag move” in an interview.

Despite the separation from USADA, the UFC remains committed to a stringent anti-doping program. UFC executive vice president and chief business officer Hunter Campbell announced that the promotion would transition to Drug Free Sport International once the relationship with USADA officially concludes next year. Drug Free Sport International is a well-respected organization that handles drug testing for several major sports leagues and organizations, including the NFL, NCAA, MLB, and NBA.

Jeff Novitzky, the UFC’s senior vice president of athlete health and performance, also expressed his disappointment with USADA’s decision. He announced that George Piro, a former FBI agent, would oversee the UFC’s anti-doping program as the new independent administrator.


USADA’s involvement in testing UFC fighters, both in and out of competition, has been a fixture since July 2015. While the split between the UFC and USADA may raise questions and concerns about the future of drug testing in MMA, both organizations are adamant about their positions.

In a statement, Tygart reiterated, “We stand by our statement and credibility.” The future of drug testing in the UFC and the impact of this split on the sport remain to be seen. As fans and fighters look ahead, the need for transparent, fair, and effective anti-doping measures in MMA will undoubtedly be a central focus.


In conclusion, the UFC-USADA split has highlighted the complexities and challenges associated with drug testing in professional sports, especially in a high-stakes environment like mixed martial arts. The controversy surrounding Conor McGregor’s potential return and the ensuing break between the two organizations signal a pivotal moment in the history of MMA and its commitment to fair competition.

As the sport evolves, so too must the mechanisms in place to ensure its integrity. The transition to Drug Free Sport International and the appointment of George Piro as the new administrator will undoubtedly play a crucial role in shaping the future of anti-doping measures in the UFC. MMA fans and athletes alike will be watching closely as these changes unfold, hoping for a level playing field and a commitment to clean competition.
