During the press conference in February that officially announced Nate Diaz would replace Rafael dos Anjos and face Conor McGregor in the UFC 196 main event, Diaz accused McGregor of being on steroids.
“Steroids? Don’t be talking about steroids. Don’t be putting my name in steroids,” McGregor yelled into the microphone. “I’m major against that. Don’t put my name in with steroids, Nate.”
According to Diaz’s boxing coach, Richard Perez, the Irishman’s defensive reaction was a sign of guilt.
“When [Diaz] told him that he was on steroids, he blew up on that. If it had of been me, I would have been laughing,” Perez told Submission Radio recently.
“When somebody is guilty about something, they get defensive,” he said. “That’s my point of view.”
McGregor’s reaction to being accused of steroid use isn’t the only thing that makes Perez believe that “The Notorious” is using performance-enhancing substances. He cites the 145-pound champion’s physique at UFC 196.
“I’m not around him. I’m not the one that really knows, but watching a guy come up from 145 to 170, you’re going to have some fat on you. Believe me, you’re going to have some fat on you somewhere, around your waist, somewhere. He didn’t have any fat at all. He was solid muscle. How are you going to build that much in two weeks and be solid muscle? He was supposed to fight at 155,” said Perez.
“Something made him build up,” he added. “To me, I feel like he’s got to be on some kind of something to get built up. He’s a little guy, and little guys can’t get all bulked up that quick.”
On March 28, the results of the UFC 196 drug tests were revealed and all fighters tested, including Diaz and McGregor returned clean results.
