Nate Diaz has accused Conor McGregor of steroid abuse as the trash talk between the two fighters heats up ahead of their upcoming clash at UFC 196.

Diaz made the accusation about McGregor as well as the entire UFC roster at Wednesday night’s press conference ahead of the March 5th fight.

“Everybody’s on steroids,” Diaz said. “The whole UFC, everybody.”

“Your teammate Gil (Melendez) and Jake (Sheilds) were two caught on steroids,” McGregor responded.

“And you and dos Anjos,” Diaz continued.

In typical McGregor-style the Dublin fighter told reporters and fans that his rivals are in fear of him.

“Nate for me was the leading auction, there were many, many auctions. In reality, many people pretended like they wanted to fight until the fight actually presented itself,” he said.

“Frankie [EDGAR]never shut-up, and then when he was given a phone call and a date, he hasn’t been seen or heard of since.

“Jose [ALDO]was in camp apparently preparing, in case Dos Anjos pulled out. Then all of a sudden Dos Anjos pulls out with a bruised foot and Jose is not fit.

“Even Nate tried to exit the fight cleanly.

“It’s always happening…they always pull out, they always run. They always make it out like they want it, but really they don’t want it. I was expecting it.”

Dos Anjos is the sixth fighter to withdraw from fighting McGregor in his last 12 fights.

“It doesn’t matter what weight division or anything, or what belt is on the line because really I should create my own belt. I am in myself my own belt. I’m fighting for my own belt.”
