The past month or so has not been good PR for the UFC, with several stars getting popped for drug use.
At UFC 200 alone, the two biggest names on the card - Jon Jones and Brock Lesnar - were caught with estrogen blockers in their system by the USADA, and look set to be hit with two-year suspensions by the UFC.
For years, the Diaz brothers have been claiming that pretty much everyone in the promotion is on performance enhancing drugs. And now Conor McGregor is agreeing with them.

On Friday, McGregor admitted that his rival is correct about the state of doping in the UFC, going all in.
"I'm happy to be tested," McGregor said on a UFC 202 conference call. "The boy is not far wrong — they f*****g all are on steroids."
"So it is f*****d up. The co-main and main at 200. That's messed up to me. I don't know."
Lesnar and Jones both failed tests for the anti-estrogen agent clomiphene. Jones was also found with Letrozole, an aromatase inhibitor that stops the testosterone from turning into estrogen in the body, in his system.
Those substances are commonly used by athletes who are coming off a cycle of steroids. Jones and Lesnar, however, claim they have no idea how it happened. Shock.
McGregor has been tested an insane 15 times by USADA over the past year. Diaz, on the other hand, has only had seven.
