Cormier called Buckley a jerk.

Daniel Cormier, a former UFC champion in two weight classes, reacted harshly to Joaquin Buckley, who made unflattering remarks about Conor McGregor's mother in a post-fight interview.

"Shut up, asshole! You might as well hear me. Your challenge to Conor is absolute stupidity. And that's what three of the most reputable people in the business are telling you. It was the worst challenge in history. Don't let a few wins make you arrogant, bro. And don't mention Audrey Cormier!" - wrote Cormier on his social media.

Recall that rude words to McGregor's mother Buckley said after his victory over Nursulton Ruziboev at UFC on ESPN 56.
