Deontay Wilder's promoter believes a unification clash with Anthony Joshua would be "massive" if the heavyweight rivals waited until all world titles were at stake.

Last week, IBF champion Joshua admitted a fight with WBC holder Wilder was inevitable, and his promoter Eddie Hearn is keen for the big-hitting champions to share the ring before the end of 2017.

Joshua battles Wladimir Klitschko at Wembley Stadium on April 29, live on Sky Sports Box Office, with the vacant WBA 'super' title also on the line.

Wilder defends his own WBC belt against Gerald Washington on February 25, but his promotional team could consider a future fight with WBO champion Joseph Parker, before attempting to unify the division against Joshua.

Lou DiBella, who promotes Wilder, exclusively told Sky Sports: "If down the line, you're looking at Joshua and Deontay, two good looking, well spoken, massive heavyweights with tremendous credentials were to meet for a total unification of the heavyweight division - that's a massive fight."

Joshua has been building his profile in America at a joint press conference with Klitschko in New York, after attracting a crowd of 90,000 to the national stadium in London.

DiBella is fully aware of Joshua's popularity in the UK and says he has the necessary qualities to make a big impact in the States.

"Joshua is a massive star already in the UK," said DiBella. "He clearly has tremendous ability, power, he looks the part, he's got the amateur pedigree, the gold medal. He's got the package."

Washington was named as a replacement opponent for Wilder after original challenger Andrzej Wawrzyk tested positive for a banned substance.

DiBella expects the 6'6" tall unbeaten Californian to supply a tough physical test for Wilder, who has recovered from surgery on a broken hand and torn bicep.

"He was a star college football player," said DiBella. "He's a physical specimen and he's a great athlete.

"Deontay is familiar with Washington's style, he's seen him fight. I think it's a more testing fight than Wawrzyk would have been."
