Conor McGregor

It was only a matter of time, but trash-talking has begun for the upcoming Conor McGregor-Nate Diaz fight at UFC 202.

During a pre-press conference in Las Vegas on Wednesday (Aug. 17), the two butted heads, resulting in a cursing match and things being thrown.

McGregor showed up late, and immediately took shots at Diaz. “I’m ready for whatever he has to bring,” he said, before Diaz got up from the podium and walked off the stage.

Diaz would make his way back into the crowd while McGregor was answering a question about the possibility of the two men engaging in a third fight if he wins at UFC 202. Several moments later, Diaz started yelling, “F*ck your whole team!”

“F*ck your whole team!” McGregor yelled. “You little crackhead asses. You’ll do nothing!”

Diaz responded by walking through the crowd with his team and giving McGregor the finger.

“Shut your f*cking mouth, you’ll do nothing!” McGregor said. “You’ll do f*cking nothing! Not one of yous will do nothing! Get the f*ck outta here! Get the f*ck outta here!”

From there, Diaz threw a water bottle at McGregor, and McGregor starting throwing them back.
