Since turning professional after winning gold at the 2012 Olympics, Anthony Joshua has been with the broadcasting giant.
In 2015, he fought on Sky Sports Box Office against bitter rival Dillian Whyte and has since remained a PPV star.
However, Joshua - who is currently training with Robert Garcia ahead of facing Oleksandr Usyk for a second time - is no longer contracted to fighting on Sky after his deal expired in September.
The Sun have reported that DAZN are the front-runners to secure his signature despite originally believing they were out of the picture.
A major factor has been promoter Eddie Hearn. The Matchroom mogul - who signed a five-year deal in 2021 to exclusively showcase all of his fights on DAZN in the UK - also penned a contract to promote the rest of Joshua's career as a boxer.
Joshua - who will fight Usyk in a bid to become a three-time heavyweight world champion this summer in Jeddah, Saudi Arabia - has admitted he will fight the southpaw differently in the second encounter after being outboxed in the first.
The Ukrainian pound for pound star outpointed Joshua at the Tottenham Hotspur Stadium in London to become a two-division world champion.
July 23 was the original date of the rematch but due to things taking longer than planned, Eddie Hearn has hinted it will now be August 20 so that they have enough time to promote the heavyweight spectacle.
The ex-cruiserweight king is hopeful of AJ remaining on Sky Sports.
I've heard those rumours but I'm as much in the dark as you are. I hope he does stay with Sky if I'm honest with you," Nelson told Planet Sport.
"I hope if what you're saying is true, saying the best platform for pay-per-view is Sky, to me that's common sense. And I'd say that even if I worked for DAZN and BT.
"You got to go where the highest numbers are in regard to pay-per-view event or a track record of the highest numbers have been. And so, he's making a business decision that works the best for his career.
"And even now AJ doesn't hold a title but I'm quite sure he can command a massive audience when he fights. So why would he not do that, this is business."
