CONOR MCGREGOR may not have pulled off boxing's biggest upset but the Irishman's fight against Floyd Mayweather is set to go down in the history books.
The Irishman lost his world title bout by a technical knockout in the tenth round against reigning light middleweight champion Floyd Mayweather at the T-Mobile Arena in Las Vegas.
But with swarms of Irish fans attending the fight and flocking the streets of Las Vegas, as well as fans back in Ireland and Britain staying up until 5 am and paying the £20 pay-per-view fee, the fight is expected to be one of the highest grossing ever.
McGregor weighed in at 153lbs, one pound below the division limit while Mayweather tipped the scales at 149.5lbs.
The 29-year-old Irishman could now be set to make an estimated $70million dollars from the historic fight after ticket sales were priced between £2,000 and £20,000 along with historic box office figures across the world, particularly in the United States.
Mayweather stands to make $240million after the viewing figures surpassed that of his fight against Manny Pacquiao in 2015 where he pocketed close to $230million.
Despite the 714-day layoff since his last fight against Andre Berto, Mayweather proved his worth as the greatest defensive boxer of all time throughout the fight.

McGregor is synonymous for his explosive aggression that has seen him come to dominate the UFC since he turned professional in 2009 with seven knockout wins in the last four years.
But in the end he was not a match for Mayweather who grinded the Dubliner down with methodical jabbing.
McGregor could be heard having animated discussions trainer John Kavanagh in between rounds but they could not engineer a tactic to trouble Mayweather.
The UFC Lightweight and Featherweight World Champion with a record of 21-3 was dependent on the 11-year age gap and his 74-inch reach, two inches longer than Mayweather's to dethrone the champion in what was the Irishman's first professional boxing bout.
But despite his sublime combat ability, the Crumlin native could not overpower Mayweather, who has yet to be knocked out as a professional.
The 40-year-old Mayweather is now 50-0 for his professional career and has cemented his place in the pantheon of boxing alongside former champions Muhammad Ali, George Foreman and Mike Tyson.
