McGregor commented on the mess Friday on Twitter, calling Aldo a “little weasel” and saying he had been tested — urine and blood — on May 23. Aldo will defend his featherweight title against McGregor in the main event of UFC 189 on July 11 in Las Vegas.

On Thursday, an agent representing the Nevada Athletic Commission, Ben Mosier of Drug Free Sport lab, went to Aldo’s gym, Nova Uniao, in Rio de Janeiro to collect a urine sample for testing from Aldo. Aldo’s manager and coach Andre Pederneiras was suspicious about Mosier and contacted the Brazilian MMA Athletic Commission (CABMMA), who said they were not informed that Mosier would be coming.
Aldo gave Mosier the sample, but after Brazilian police were called they learned that Mosier did not have the correct work visa. Mosier was fined $130 and given eight days to leave the country. The urine sample provided by Aldo was discarded.
On Friday, a World Anti-Doping Agency accredited collector and CABMMA official went to Nova Uniao to collect a urine sample from Aldo. The sample will be sent to WADA-accredited Sports Medicine Research & Testing Laboratory in Salt Lake City, according to CABMMA.
“That’s normal,” Aldo told Combate on Thursday. “We reached a point in this sport that not only me, but every fighter has to go through this. This is my first time in Brazil. I think the Brazilian commission should be the one handling this, for the fact that I live here. But that’s not an issue. It’s nothing for me. Fight, pee, it’s the same thing to me.”
McGregor has said that he believes Aldo used performance-enhancing drugs in the past and that it might be “Brazilian culture.” Aldo shot back that he believes McGregor is using some kind of PEDs to make 145 pounds.
The UFC has spent more money promoting Aldo vs. McGregor, the biggest fight in featherweight history, than any other main event ever. That includes teasers and a commercial airing during the NBA Finals, a five-country World Tour and 10 UFC Embedded episodes leading up to the fight.
