After watching Topuria lose at UFC Freedom 250, Crawford mocked the earlier callout.

“This the guy that said he would knock me out and whoop me and Shakur at the same time?” Crawford wrote on X, followed by laughing emojis.

McGregor quickly came to Topuria’s defense and questioned Crawford’s willingness to step into the Octagon.

“What the f**k are you saying? You can wrestle, yet you are afraid of an MMA fight. That to me is pitiful.

“The kid was beaten in an MMA fight, of which you don’t have the courage for.

“What the f**k was with all these little boxers at this show, yet no MMA fighters?”

Crawford responded by dismissing the idea that he needed to prove himself in another sport.

“Shut yo drunk as up and get ready for yo fight. He got his ass whoop like you did running yo mouth. I don’t have to come and fight in the cage. That’s the joy of boxing yall come to us we don’t have to come to yall.”

McGregor has long championed crossover bouts between boxing and MMA athletes, having famously faced Floyd Mayweather Jr. in a boxing match in 2017. Crawford, meanwhile, has shown little interest in leaving the ring, even after Topuria publicly floated the possibility of facing him in a boxing match.

For now, the latest chapter in the boxing-versus-MMA rivalry appears destined to remain on social media rather than inside either the ring or the cage.
