David Higgins, manager for former WBO heavyweight champion Joseph Parker, says his boxer would be open to the possibility of a final WBO eliminator against unbeaten puncher Daniel Dubois.
Parker is ranked at number two by the sanctioning body, while Dubois is ranked at number three.
The current WBO champion is Anthony Joshua, who has already been ordered to make a mandatory defense against the WBO's number one, Oleksandr Usyk.
Joshua will first make mandatory defense against the IBF's top man, Kubrat Pulev.
And Usyk will likely risk his ranking against veteran Derek Chisora on a date in March or April.
Parker is going to return to the ring on February 29 in Texas, against Polish giant Mariusz Wach.
Dubois is being positioned for a high-stakes showdown with undefeated Olympic medal winner Joe Joyce on April 18.
Sooner or later, the WBO will select two of the top contenders for a final eliminator - and Parker vs. Dubois would be a good possibility if they continue to hold their rankings.
"I think anything is possible," Higgins told Sky Sports. "It's great that Dubois is making waves and provided he keeps doing that, it's very possible that Joseph Parker would fight him. They just have to keep heading in the right direction. I personally think Joseph Parker has too much pedigree and too good a head on his shoulders for Dubois.
"Dubois clearly has great power. There's a lot of unknown there. I think Parker has got too much class. If we were ordered to fight, or put in that position, it's something that could be discussed down the track."
