FLOYD MAYWEATHER has suggested he is open to a showcase fight with UFC champion Conor McGregor after inviting the Irishman to set up a bout on social media. 

The five-weight boxing world champion said yesterday that he was 'happily retired' amid speculation that a showcase fight with the MMA star could take place.

But after McGregor tweeted a picture of himself in Las Vegas with the caption: "Floyd has retired on my arrival", Mayweather appeared to change his mind.

Mayweather, who holds a 49-0 record and hasn't fought since September 2015, invited McGregor to 'take care of your business with the UFC' and begin talks for a fight.

In a post on Twitter, the American wrote: "Listen, Conor Mcgregor, if you really want to get this fight done...take care of your business with the UFC and then have your people get in touch with my people."

McGregor has already obtained a boxing license in his pursuit of a cross-sport showcase and became UFC's first simultaneous two-weight champion in November before vacating his featherweight belt.
