Anthony Joshua meets Otto Wallin in the main event while Deontay Wilder faces Joseph Parker in the co-feature. If both Joshua and Wilder win — no foregone conclusion — they have a deal in place to finally meet on March 9 in Riyadh, sources told ESPN.

Also on the undercard: ESPN's No. 1 light heavyweight, Dmitry Bivol, and No. 1 cruiserweight, Jai Opetaia.

The following week, Naoya «The Monster» Inoue attempts to become an undisputed champion in a second weight class in 12 months with a fight against Marlon Tapales on Tuesday in Tokyo (ESPN+, 3 a.m. ET).

This is all subjective. After all, most of the fighters on this list will never face each other, sometimes even when they're competing in the same weight class. That's the reality of today's fractured
