• Kubrat Pulev is the IBF’s mandatory challenger and will either face the winner of the Joshua-Klitschko bout or he will compete for the vacant title against David Haye
• Luis Ortiz is the WBA’s mandatory challenger and will either face the winner of the Joshua-Klitschko bout or he will compete for the vacant “Super” title against Alexander Ustinov
• Shannon Briggs will face Fres Oquendo for the vacant WBA "regular" heavyweight title
• Alexander Ustinov's manager has stated that his charge could face David Haye for the WBA’s vacant "interim" heavyweight title
• Hughie Fury is likely to be installed as the mandatory challenger for Joseph Parker’s WBO crown, because David Haye (being the top-rated challenger) is tied up with the Tony Bellew fight
• Deontay Wilder is obliged to face the winner of the final eliminator for the WBC title, which means he could defend his championship against whoever emerges victorious from Alexander Povetkin (doubtful), Bermane Stiverne or Dillian Whyte
The winner of the Joshua-Klitschko bout will face a tricky situation trying to retain ownership of both the WBA “Super” and the IBF titles due to having to fulfil commitments to face both organisations' mandatory challengers, with a similar situation compelling Tyson Fury (when he was the champ) to vacate his newly-acquired IBF strap.
Is my understanding correct or are there some errors?
