Details are still to be confirmed but the fight will be a pay-per-view event, organised by Showtime Sports.

The price has not been decided, though it is expected to be at or near the $99.95 charged for Mayweather's 2015 fight with Manny Pacquiao that drew a record 4.4 million pay-per-view buys.

"This is really an unprecedented event," said Stephen Espinoza, who heads Showtime Sports. "Really we haven't seen anything in modern history that resembles it, it's impossible to predict how many sales this will do."
