Dillian Whyte, who currently holds the WBC Silver belt, is number one in the rankings, but as Sulaiman pointed out, was overlooked by the WBC for a future Wilder shot due to his failure to accept an eliminator fight with Luis Ortiz.
"The mandatory challenger is Dominic Breazeale," the WBC figurehead stated. "Last year he was contracted to fight a final elimination bout versus Bermane Stiverne.
"When Luis Ortiz could not fight Deontay Wilder, Bermane Stiverne got the fight and Breazeale was left with a contract. The replacement for Breazeale was Eric Molina.
"The condition was that if Breazeale won he would become mandatory as per the contract he had.
"Dillian Whyte is the WBC silver champion, but is not mandatory. The WBC offered him to fight a final elimination bout to enforce a second mandatory on the division against Luis Ortiz, but Whyte did not wish to fight such," said Sulaiman.
