The station is showing each of his twelve UFC fights back to back over a three-hour binge of Octagon action.
McGregor’s first bout was against Marcus Brimage in Sweden but it was not really until the fight against Chad Mendes, his 6th UFC outing that he really captured the public’s imagination.
It was supposed to be Jose Aldo in against him but an injury to his hand meant Mendes stepped in at late notice.
The fight against Aldo was a massive triumph of hype over substance with the fight lasting 13 seconds and McGregor getting his first title.
That will be on air this evening at 2214.
There then followed two fights against Nate Diaz, and then his second title beating Eddie Alvarez.
Time out for the Mayweather circus was followed by his second defeat in the mad scenes in Las Vegas after his loss to Khabib Nurmagomedov.
His latest comeback and a short-order win against Donald Cerrone round out the night if that’s your kind of thing.
Bear in mind though if it is not, that this was a man who was voted by the Irish public as the Sports Personality of the Year in 2016.
And to be fair there are not many of our sporting heroes who would get this treatment from a broadcaster like BT Sport.
