Last Updated: 21/08/17 5:17pm
Floyd Mayweather-Conor McGregor fight week has started and we answer all the key questions about what to expect ahead of the Las Vegas showdown, live on Sky Sports Box Office.
The American superstar has come out of retirement for a groundbreaking 50th professional bout against UFC champion McGregor, who is switching combat codes to take part in his first professional boxing fight.
A massive worldwide audience will be watching when the first bell rings in the early hours of Sunday morning, but there is plenty to enjoy beforehand as we build towards this unique encounter, live on Sky Sports Box Office.
What is coming up?
We'll get our first glimpse of McGregor and Mayweather when they make their 'Grand Arrival' on Tuesday, which should be an ideal stage for the two showmen to flaunt their extravagance and issue more pre-fight taunts.
This entertaining war of words will resume in Wednesday's Mayweather-McGregor press conference as both men continue the psychological warfare, with Nathan Cleverly and the rest of the undercard holding their own presser on Thursday.
There will be a final chance for Mayweather and McGregor to flex their muscles and share a last face-off at the weigh-in, which is likely to be staged in front of a huge attendance.
Where is the fight?
A lucrative fight of this magnitude could only be staged in Las Vegas and a crowd of A-list stars from the movie and music world are expected to attend the T-Mobile Arena.
This 20,000-seated venue, costing $375m, was only finished in April last year, but has already hosted concerts for Jay Z and Lady Gaga, along with McGregor's rematch win over Nate Diaz in UFC.
Who is on the undercard?
Welshman Cleverly will make the first defence of his WBA light-heavyweight title against Badou Jack, a member of Mayweather's 'The Money Team' promotional stable.
Mayweather's protege Gervonta Davis also defends his IBF super-featherweight belt against Francisco Fonseca, while former Team GB boxer Savannah Marshall makes her pro debut, and unbeaten cruiserweight Andrew Tabiti is targeting a 15th straight win.
When do they get in the ring?
Mayweather and McGregor are expected to make their ring walks after 4am, but these two rivals might employ delaying tactics for some last minute mind games.
Make sure you set a loud alarm call, or have a large cup of coffee at the ready if you are planning a marathon night of boxing.
Where can I watch it?
Sky Sports Box Office will show the undercard and the massive main event of Floyd Mayweather-Conor McGregor, with live coverage of a spectacular night of boxing starting at midnight.
