Tyson Fury would only have to give Dillian White 20 percent of his potential performance purse.
The WBC made White a mandatory challenger for the green and gold belts in October, but a deal has been delayed by a dispute over money.
1 contender since 2017, pushing for a 40 percent split based on his interim-champion status.
But Team Fury – led by UK promoter Frank Warren and his US colleague Bob Arum – insisted that White is only worth 20.
White took the WBC to an arbitration case to increase his potential pay packet.
But SunSport understands that the Mexico-based sanctioning body has now ruled that 33-year-old White will get only a fifth of his potential unpredictability.
Fury, also 33, wants to fight in early March and White will have the option of accepting the terms for a UK showdown this spring.
Or Fury already has two potential adversaries on both sides of the pond.
Finnish legend Robert Helenius is already set to fight Fury in the UK’s homecoming battle, subject to coronavirus restrictions allowing a full house.
And if an appearance ban looks like hurting Fury’s earning potential on home soil, he could return to Las Vegas where he likes the idea of facing Andy Ruiz Jr.

Purse bids for the bout will take place on January 11 at WBC Headquarters in Mexico City.
But, with travel restrictions a constant hurdle, interested parties can participate via Zoom.
The top ranked brand of Warren and Arum will bid to host Clash on BT Sport.
While Eddie Hearn — who is a longtime White collaborator but has no contract with the free agent — will try to take it off for the streaming app DAZN.
Sky Sports will also be interested as White has been a huge hit on its pay-per-view platform since her 2015 thriller with Anthony Joshua.
