Promoter Eddie Hearn is pushing to have Dillian Whyte to become the mandatory challenger to WBC heavyweight champion Deontay Wilder.
Whyte, who is ranked at number one by the WBC, is scheduled to face Oscar Rivas at The O2 on July 20, live on Sky Sports Box Office.
Hearn is looking to have that contest become a WBC final eliminator, with the interim-heavyweight title at stake.
Wilder will be facing mandatory challenger Dominic Breazeale on May 18th at Barclays Center in Brooklyn, New York.
Hearn believes his boxer got stepped over in favor Breazeale.
He wants the winner of Whyte vs. Rivas to be mandated to fight the winner of Wilder vs. Breazeale.
"Everything that he's done in that division, all the defences of his WBC 'silver' title, a couple of world title eliminators, and him ranked No 1 for god knows how long, and yet someone who is ranked four or five becomes the mandatory," Hearn told Sky Sports.
"We're pushing hard for a resolution, and we want the Oscar Rivas fight to be for the mandatory position with the WBC and for that interim world title. We'll see where that goes. We're all trying to come up with a resolution that's fair and we haven't yet, so we're still pushing. We want the Rivas fight to be for something very significant for the WBC and that's probably an interim world title fight and to become mandatory for the winner of Deontay Wilder against Dominic Breazeale."
Whyte is also ranked in the top spot by the WBO, but Hearn expects Oleksandr Usyk to be names as their next mandatory challenger to WBO champion Anthony Joshua.
"That mandatory is not due to be called until September 31," said Hearn. "My gut feeling is they'll still call Usyk for that mandatory spot, but if Dillian gets that mandatory, great."
