After signing what he called a “record-breaking deal” with the UFC for his hyped superfight with Floyd Mayweather, Conor McGregor is calling out the boxer.

Over the weekend, the UFC star took to social media to taunt Mayweather, saying it’s all on him now to make the fight happen.

McGregor posted a photo of himself in the gym with his trainers, after a workout. The caption: “Solid work today. Sign your end Floyd or you are just a mouth.”

They say I've got no chance. But they say that every fight.

Last week, UFC president Dana White said he had come to terms on a deal with McGregor and is now moving onto Mayweather’s camp to begin negotiations.

“The McGregor side is done. I’m starting to work on the Mayweather side now,” White said. “I’m not saying the fight will happen, but I’ve got one side done. Now it’s time to work on the other. If we can come to a deal with Haymon and Mayweather, the fight’s gonna happen.”

Terms of Conor’s deal with the UFC is currently unknown, but previous reports said he could get a purse of around $75 million — the largest ever for a UFC fighter and most-ever for McGregor.
