Joseph Parker's team say they would welcome a fight against David Haye which would put the New Zealander's IBF mandatory world title challenge at risk but would have the potential to earn him a massive pay-day and raise his profile in Great Britain to a new level.
Duco Events promoter Dean Lonergan said a fight would between the fast-rising 24-year-old Kiwi, and 35-year-old Haye, a two-weight world champion on the rebound after a long lay-off, would potentially be more lucrative than a world title fight for Parker.
"If you put Joseph Parker and David Haye in a ring, the interest in England would be massive," Lonergan said. "The pay-day for both guys would be very, very large. Potentially, for Joseph it would be bigger than a title fight.
"When we go to a world title fight with Anthony Joshua, Joshua is definitely on the 'A' side and we would be the challenger. If Joseph fought Haye, you'd like to think there would be an equal split and that we could do a co-promotion up there because we're bringing the mandatory."
Lonergan has been in discussions with Joshua's promoters Barry and Eddie Hearn about having Parker fight on a Joshua undercard in London and possibly in November. That would raise the profile of Parker in Great Britain ahead of a possible title challenge against Joshua in the New Year.
