That's a fired-upConor 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."
