Boxing in 2021: Ranking the 'final four' heavyweights in order of most likely to end up a four-belt champion

Who among Anthony Joshua, Tyson Fury, Deontay Wilder and Oleksandr Usyk reaches undisputed status?

With Saturday's bout between Anthony Joshua and Oleksandr Usyk, the heavyweight division starts down a path many hope ends with an undisputed heavyweight champion. Should things go according to plan, the winner of Joshua vs. Usyk will clash with the winner of the trilogy fight between Tyson Fury and Deontay Wilder, scheduled for Oct. 9.

WBA, IBF and WBO champion Joshua was previously scheduled to meet WBC champ Fury when Wilder managed to enforce his contractually-obligated rematch with Fury via arbitration. Joshua moved along to face mandatory challenger and former undisputed cruiserweight champion Usyk with the goal of still unifying the championships in his next fight.

While nothing is ever guaranteed, especially when it comes to boxing, the sport seems just one fight away from crowning an undisputed heavyweight champion. CBS Sports boxing experts Brian Campbell and Brent Brookhouse have ranked who in this unofficial tournament is most likely to be the man to hold all four recognized heavyweight world titles.
