Eddie Hearn, who promotes IBF, IBO, WBA heavyweight champion Anthony Joshua (20-0, 20 KOs), believes a unification with WBC champion Deontay Wilder (39-0, 38 KOs) is such a massive fight that you can do it twice.

Both champions have very tough assignments coming up.

Wilder defends his title next Saturday night, against undefeated puncher Luis Ortiz (28-0, 24 KOs) at the Barclays Center in Brooklyn, New York.

And Joshua will fight on March 31, in a high stakes unification with WBO heavyweight champion Joseph Parker (24-0, 18 KOs).

Hearn sees no issue with having Joshua and Wilder collide in the United States - like staging the fight at the T-Mobile Arena in Las Vegas.

“We’d fill up that arena with Brits,” Hearn said to Kevin Iole of Yahoo Sports regarding the idea of staging Joshua-Wilder fight at T-Mobile Arena in Las Vegas.

“We’re open to a U.S. fight for the Wilder fight. I think it makes sense to do two, not because we want any rematch clause, but because it’s the biggest fight in world boxing. Why not run it twice? The fans would love to see it. Run it twice. One at Wembley and once in Vegas, or at the Barclays Center in Brooklyn, somewhere like that."

Hearn has already told BoxingScene.com that he's possibly going to stage Joshua's Unites States debut in the summer, at the Barclays Center, and undefeated contender Jarrell Miller is the leading candidate to fight him.

Joshua is arguably the biggest ticket draw in all of boxing. He drew a record 90,000 fans for his April 2017 TKO win over Wladimir Klitschko at Wembley in London, 78,000 came to watch his TKO of Carlos Takam at Principality in Cardiff, and the same number or more is expected for when he faces Parker at Principality.

Hearn believes a fight between Joshua and Wilder will easily bring a 90,000 number to Wembley.
