Four days of a contentious international world tour came to a fitting close on Friday when global superstars Floyd Mayweather and Conor McGregor faced off for the final time on their three-country excursion at London's Wembley Arena.


What follows next before the boxing legend and UFC superstar meet Saturday, Aug. 26 on SHOWTIME PPV live from T-Mobile Arena in Las Vegas?  Forty-three days of grueling preparation, speculation and pundit analysis as the world's best combat fighters continue their collision course toward an event that has become a global phenomenon.
 
In front of a capacity crowd at a famed venue that has hosted acts ranging from The Beatles to the Olympic Games, Mayweather and McGregor capped off nearly a week of intense gamesmanship that grew with each tension-filled face off.


 
"You're the student and I'm the teacher," said Mayweather, a once-in-generation talent who has dispatched at least five future Hall of Famers en route to an unblemished 49-0 professional record.  "On August 26, I'm going to take you to school."
 
McGregor, an unrivaled figure in mixed martial arts who has transcended his sport to become a must-see attraction, answered, "In six weeks, I'm going to sleep this fool. And when I sleep him, I'm going to bounce his head off the canvas as well."
 
The World Tour may be over, but the show has just begun.
