Tyson Fury has vowed to "annihilate" Dillian Whyte, who was confirmed on Saturday as his next opponent in an all-British bout for the World Boxing Council heavyweight title.
The fight must take place within the next 90 days, with Cardiff a potential host, after Fury's promoter Frank Warren won the purse bid with an offer reportedly worth £31 million (NZ$63m).
Heavyweight boxing's merry-go-round saga has finally reached a resolution as Fury declared he would give Whyte, the WBC's mandatory challenger, the "best hiding he's ever had" in a video posted on social media.
Meanwhile, promoter Eddie Hearn claimed Fury's demands were unrealistic for Anthony Joshua to step aside and allow him and Oleksandr Usyk to contest the undisputed heavyweight championship.
With time clearly running out for any step-aside deal with Joshua to be finalised, speculation came to an end in Mexico City at the HQ of the WBC at 6am on Saturday.
