Only the WBC with PBC can manage to pull off a vacant title fight where both guys are coming off a loss.
It always sounds like the WBC is just saying that they have no use for the champion and they want their sanctioning fees. Same with Haney. Can´t fight? No problem, we will just give the belt to someone else who has a fight lined up. Keep the money train rolling, baby! This is what interim titles are for. If the champion can not oblige my his mandatory obligations, the ABC will sanction a fight for the interim championship. Basically keeps the top guys in rotation and active, so that the entire division won´t have to wait on the champion.
WBC hypocrisy at it's finest. The WBC didn't strip Miguel Berchelt of the belt despite him also testing positive and having a fight lined up like Oubaali.
