Conor McGregor has been accused of 'crying' about injuries by UFC welterweight champion Kamaru Usman.
The Notorious is currently sidelined after breaking his leg during his trilogy fight with Dustin Poirier in July, but has become embroiled in a Twitter spat with fellow UFC star Jorge Masvidal.
McGregor criticised Masvidal for pulling out of his fight with Leon Edwards due to injury, which prompted Usman to join the conversation.
McGregor tweeted: "It’s also Jorge Masvidal birthday but he a bitch for bottling the fight against Leon. F*** your 'injury'.
"You sign to fight, you fight. Strip that belt from him that he never even won. Hoe in a housecoat. The f*** was that about as well? Last seasons Versace house coat hahaha wtf."
Usman replied: "You should be quiet. You cry about injuries more than anyone after you get your ass whipped. Foot,Ankle, Shin what else am I missing?"
But McGregor hit back at Usman, claiming that 'The Nigerian Nightmare' lacks originality.
He said: "Ye you’re missing something bro for sure. Don’t quite know what tho. Originality maybe?
"I don’t know, something. It’s like, nobody cares. No one cares what the f*** you’re at.
"And you try so hard too, I just don’t know. Somethings missing for you tho for sure. God bless anyway."
McGregor is set to return to the Octagon next year and he previously has hinted at challenging for the 170lbs belt.
He twice fought Nate Diaz at welterweight and also destroyed Donald Cerrone in 40 seconds at 170lbs in 2020.
