Conor McGregor Threatens Justin Gaethje, ‘You Are F**king Dead’

“I am going to f**king butcher you”

That’s a fired-up Conor McGregor making some serious threats to Justin Gaethje — telling the UFC’s interim lightweight champ that he’s coming for Gaethje’s head.

“Your teeth. I’m going to put them on a f**king necklace,” Conor said to Justin.

In an angry Twitter rant Monday, McGregor says he wants to fight Justin next — and it seems the hostility comes from a 2019 tweet Justin sent criticizing Conor as a “sh*t human, father and husband.”

Conor remembered the tweet and responded …

“Speak on my skills as a father? You are f**king dead.”

McGregor added, “Don’t ever say you represent the great nation of the United States of America ever again.”

For his part, Justin has been calling for a fight with Conor for a while — telling TMZ Sports back in 2019 he actively tried to get Conor to sign a contract but the Irishman wouldn’t do it.

“I wrote him a message like f**king 7 months ago just trying to be his friend. I’ve tried every route,” Justin said.

“I’m trying reverse psychology. I’m trying to be his friend. I’m trying every f**king route that there is to draw this man out. And I can’t draw him out. And he’s calling out Frankie Edgar. So, it’s a slap in the face to me, to all the lightweights, and to really the standard that we f**king do here.”

Of course, Justin beat the hell out of Tony Ferguson at UFC 249 on Saturday … and says he now wants to fight Khabib Nurmagomedov for the real lightweight title.
