McGregor fight to break pay-per-view TV records
Conor McGregor's hugely anticipated fight with Floyd Mayweather is set to be the highest-grossing pay-per-view event of all time.
Some 50 million people in the United States alone are expected to tune in for the fight in Las Vegas.
Millions more will be watching worldwide on Saturday night as fans will find a variety of ways to tune in to the bout.
Although Sky said it cannot reveal the full number subscribing until after the pay-per-view event, it said it has been selling "phenomenally well".
It is understood many subscribers will leave it until the day of the fight to buy their subscriptions.
Last night, McGregor and Mayweather once again traded verbal blows at their last press conference before their highly anticipated fight.
The pair once again squared off at the press conference, in which an ever-defiant McGregor proclaimed: "He's not a quarter of the man I am."

The Irishman - who was almost an hour late for the event - warned: "Keep your hands up or down, I'm going to break what's in front of me. I've taken the rules very seriously. I will go out and I will perform."
The much-awaited fight card will begin at around 4am Irish time (10pm local time) and take place in the Las Vegas T-Mobile Arena. While millions will be tuning in, there are a number of tickets for the fight still available.
It is understood around 1,000 tickets are still available on the secondary market. Ticket prices have been dropping in the resale market - with some available for less than $1,300 (€1,100) on Tuesday. Prices had started at $2,500 (€2,116).

Conor McGregor's local Crumlin Boxing Club and Bluebell United Football Club are among the venues showing the fight live.
Dublin nightclubs will also be showing the fight live, with The Wright Venue in Swords, Buck Whaley's on Leeson Street and Sin Nightclub amongst them.
