Sign the contract - Mayweather taunts 'b****' McGregor
Floyd Mayweather Jr labelled Conor McGregor a "b****" on Tuesday as he once again called out the UFC star and suggested he would immediately send a signed contract to the Irishman in a bid to make a fight between the two a reality.
Mayweather and McGregor have been engaged in seemingly endless verbal warfare over a potential bout, although a deal has still to be agreed for the retired boxer and mixed martial arts expert to go head-to-head.
Addressing reporters in London, Mayweather suggested he is prepared to force the issue.
"If he [McGregor] really wants to fight, sign the contract," said Mayweather.
"You keep telling everybody 'I'm scared of you, I'm scared of you' - this is what I'm gonna do, I'm gonna get a contract typed up tonight, I'm gonna sign it and I'm gonna fax it over to Conor McGregor and see if he's gonna sign it.
"Conor McGregor, you a b****."
In an interview with Sky Sports, Mayweather added: "Can the fight with Conor McGregor happen? Absolutely - it is possible. We just don't know at this particular time.
"We don't know what the future holds or if he wants to fight. We will have to see."
