Conor McGregor's potential fight with Floyd Mayweather has moved closer with reports a venue has already been booked.

Las Vegas' T-Mobile Arena has been provisionally booked for June 10, however no agreement has been made between the duo.

Meanwhile, Floyd Mayweather has revealed he is "officially out of retirement" in order to fight UFC champion Conor McGregor.

A bout between the five-weight boxing world champion Mayweather and UFC's biggest star has been rumoured for weeks.

Mayweather, 40, has previously stated he would only return to the ring to fight the Irishman and, on Saturday, he gave the clearest indication yet that it could happen.

Speaking in Liverpool on the latest leg of his UK tour, Mayweather said: "I'm officially out of retirement for Conor McGregor, today.

"If he's really real, like he's says he is, if you really want to fight, just sign the paper."

The T-Mobile Arena opened last year, with McGregor beating Nate Diaz there last August.

The booking was first reported on Sunday night.

With just under three months to go until the June 10 date, there is a slim chance of getting everything signed off in time to allow for the pre-fight promotion.
