A high stakes unification fight between heavyweight world champions Britain's Anthony Joshua and New Zealand's Joseph Parker could be confirmed in the next two weeks, according to Joshua's promoter Eddie Hearn.

Hearn told Sky Sports there's a good chance Parker's promoter David Higgins will fly over to London in the next week to try and close the deal for a bout in March or April.

There are also talks with WBC champion Deontay Wilder, but their side wants a lot more money than what Parker is requesting.

"There are two perfect fights for AJ - Parker and Deontay Wilder. The Wilder fight is unrealistic because of what they want. The Parker fight is a lot closer," Hearn said.

Joshua wants to add Parker's WBO belt to his collection but Hearn told Sky Sports they'll have to consider an alternative fight if a deal with Parker is not reached.

There are several options being held as backups to Parker - including a rematch with Dillian Whyte or a fight with undefeated Jarrell Miller.

"We may look at a WBA mandatory, Dillian Whyte or going to the States to fight Jarrell Miller," Hearn said. "There are options but the aim is to become the undisputed world heavyweight champion.

"Parker is the frontrunner, he's the guy we want. But we can't be in a position where this goes on for three weeks then falls through."

Joshua was in action last month, when he retained his IBO, WBA, IBF world heavyweight titles with a tenth round stoppage of mandatory challenger Carlos Takam at Principality in Cardiff, Wales. Parker made a mandatory defense of the WBO belt back in September, when he traveled over to Manchester to win a twelve round decision over undefeated Hughie Fury.
