Below are the announcements for cruiserweight and heavyweight:
Heavyweight: Champion Deontay Wilder (United States)
When Wilder was injured in his last fight on July 16, an interim title fight was ordered between No. 1 ranked Alexander Povetkin of Russia and No. 2 ranked Bermane Stiverne of Haiti/Canada. Povetkin tested positive for a banned substance before the fight and the WBC will review the mandatory status.
Cruiserweight: Champion Tony Bellew (Great Britain)
Bellew requested approval from the Board of Governors for a fight in the heavyweight division against David Haye, and the Board supports his request. Bellew will remain cruiserweight champion until he informs the WBC whether he will continue to fight as a heavyweight or return to the cruiserweight division.
In the meantime, the WBC has ordered an interim title fight between No. 1 ranked Mairis Briedis of Latvia and No. 2 ranked Marco Huck of Germany. The free negotiation period has begun and if no agreement is reached, a purse offer will be held on January 14 or 15.
If Bellew decides to return to cruiserweight, the winner of the interim fight will be his mandatory challenger. If Bellew decides to continue at heavyweight, the winner of the interim fight will become world champion. Since the last mandatory defense took place in December, 2013, the WBC ordered a tournament between the top four available contenders to determine the next mandatory challenger.
The World Boxing Council ratings for December are set to be announced imminently after the WBC Convention closed
