Anthony Joshua is widely expected to make the second defence of his IBF world heavyweight title in late November or early December, but this time in Wales as opposed to what's become his home turf of the O2 Arena.
Promoter Hearn has his sights set on the Millennium Stadium in Cardiff for a huge heavyweight night that is likely to include IBF mandatory challenger Joseph Parker colliding with the heavy-hitting David Price, as well as an all-British battle between rivals Dillian Whyte and Dereck Chisora.
"Everything makes sense at the moment but for all of it to fall into place, so much needs to happen," Hearn told Sky Sports.

"There are two parts to every fight. Those three fights, that's six parts that have to fall into place and that's six fighters accepting the terms. We've got six hurdles to overcome and so far, Joshua's the only one who's not a problem. He'll fight anyone.
"Price is interested in the fight and Parker is interested in the fight but we need to talk terms with them.
"As for Chisora against Whyte, I think we all know they both want to fight, but we haven't really discussed the terms yet, so there is so much that needs to happen. But if it is big enough and the numbers make sense, it can happen."
Parker has no need to fight Price whatsoever. If he sat and waited for next year, he would get his shot at AJ regardless.
It's admirable that he wants to remain active and prove himself to the British crowds. The 24-year-old Kiwi is a dangerous knockout puncher and his eventual bout with Joshua is sure to be spectacular.
As for Whyte and Chisora, that is two bruisers who are fully prepared to slug it out. An all-British slugfest would be a terrific warmup for the main event.
Here's to hoping Hearn can make this official in the coming weeks.
