Conor McGregor vs. Jose Aldo was rebooked for Dec. 12, and "The Notorious" hopes Aldo gets tested before UFC 194.

Before pulling out of UFC 189 in July with a rib injury, Aldo was involved in a controversial drug test procedure in Rio de Janeiro, when Drug Free Sport director Ben Mosier visited Nova Uniao for an unannounced drug test. Aldo agreed to do the test, but visa issues forced Mosier to discard the urine sample.

Aldo provided a second urine sample a day later, and tested negative for banned substances. He ended up leaving the bout with an injury, and McGregor defeated late-replacement Chad Mendes to win the interim title.

After all the controversy, "The Notorious" hopes his rival is getting tested before UFC 194.

"I got tested. I get tested constantly, it's his shady ass that doesn't get tested over there in Brazil," McGregor told Combate. "All this corruption is still over there. Some police officer from the gym arrested the guy who was taking the test. That is the shadiest shit I’ve ever heard in my life. So, I take the test, he doesn't. Test his ass!"

Aldo recently spent some days in the United States to visit the Ultimate Fighter gym and be part of the "Go Big" press conference, and McGregor hopes he was drug tested by the Nevada Athletic Commission while in Las Vegas.

"He should've been tested right now, today or this whole period," he said. "If he wasn't, that's disgraceful. We'll see. I'll ask if he was or was not tested."
