With no Irish leg of the four city tour, the face-off at the Wembley Arena will be the closest McGregor comes to his Dublin home ahead of the August 26th megafight in Las Vegas.
Thus far the tour has attracted a lot of attention and controversy.
Mayweather was seen to have ‘won’ Tuesday’s opener in Los Angeles before McGregor roared back on Wednesday in Toronto. Both fighters and the event itself were then heavily criticised following a bizarre event in New York last night.
To round off the tour the light middleweight pair are now back on this side of the Atlantic.
The press conference is scheduled to start at 7:00pm.
