Brad Jacobs, COO for Top Rank, believes a heavyweight unification between champions Tyson Fury and Anthony Joshua would be a very big deal in the United States.
The fight would easily sell out any stadium in the UK, but the contest would generate more money in a United States location like Las Vegas.
Fury and Joshua may potentially fight in 2021, as the two sides are actively discussing certain terms for a two-fight agreement.
Fury has had his last four fights in the United States, with three of them in Las Vegas.
"It would be a huge fight in Britain for obvious reasons. But a heavyweight championship fight in the US is a big thing," Jacobs, representing Fury's American promoters Top Rank, told Sky Sports.
"Certainly Fury's second home is Las Vegas. All of his recent fights have been there. He has a tremendous following in the US with [American TV] pushing him and making him a star. Fury is better known in the US than Joshua. But there is time for Joshua to make a name for himself before this event takes place.
"It doesn't hurt for either guy to continue to build their profile before this fight. They are each huge names across the world. The bigger and better that becomes, the better it is for everybody."
Fury is set to make his next defense of the WBC world title. He is currently scheduled to have a trilogy fight with Deontay Wilder at the end of the year, with December 19th as the working date.
And Joshua is going to defend the IBF, IBO, WBA, WBO world titles against mandatory challenger Kubrat Pulev in the coming months.
