The Ultimate Fighting Championship has decided to end its partnership with the United States Anti-Doping Agency starting January 2024.
USADA has been the UFC’s independent drug testing partner since 2015. However, things have now seemingly turned sour over the mandatory testing window for former two-division champ Conor McGregor’s return to action. According to USADA CEO Travis Tygart, the relationship with the UFC became “untenable” over recent comments made by the promotion's leaders and one commentator. Tygart was likely referring to popular podcaster and longtime UFC commentator Joe Rogan, who recently called for the promotion to cut ties with USADA over the six-month testing window and ban on certain peptides.
