Wilder and Tyson Fury fought to a draw this past December, leaving the champion with a record of 40-0-1.
Current IBF, IBO, WBA and WBO heavyweight champion Joshua is gearing up to face Jarrell "Big Baby" Miller at Madison Square Gardens in NY on June 1st, but Hearn is already looking forward to a fight with Wilder towards the end of this year.More news: Novak Djokovic stunned by Kohlschreiber, 35, is keen to 'turn the page'
Wilder has since been ordered to defend his title against Dominic Breazeale but has reached out to DAZN - who broadcast Joshua's fights in the United States of America - to discuss a potential bout.
Two years on since Joshua defeated Wladimir Klitschko back in 2017, a fight between the two unbeaten heavyweights has been tipped to happen to determine who the best in the world is.
And with Wilder vs Fury 2 seemingly no longer on the table, Hearn believes we could see "AJ" lock horns with "The Bronze Bomber" by year's end. It has not been discussed what effect Wilder's potential relationship with DAZN could have on the chances for a rematch.More news: Trump slams handling of Brexit by UK's May
Boxingscene also reports that undefeated Polish heavyweight contender Adam Kownacki is considering offers from DAZN and ESPN. It is a six fight deal said to be in the 8-figure range.
But it seems with the 33-year-old that contract talks at agreeing fights aren't his speciality as another setback in that deal scuppered a second meeting with Fury. Wilder turned down an offer from Top Rank last month to fight this spring or early summer for $12.5 million followed by a rematch of his December 1 draw with lineal champion Tyson Fury, who recently signed with Top Rank, for at least $20 million this fall.

"DAZN has quickly become the new home of boxing by making the biggest events easily available to the fans", said Golovkin. 'But I think there's an opportunity there for someone to be a mediator to get the fight done. The service is now available in nine countries - Austria, Brazil, Canada, Germany, Italy, Japan, Spain, Switzerland and the U.S. - and plans to reach 20 markets by 2020.
