There's a new No. 1 pound-for-pound fighter, which doesn't come as a surprise. Oleksandr Usyk's victory over Tyson Fury to become the first undisputed champion in the four-belt era, and first since Lennox Lewis held three belts in 2000, catapulted him to the top spot over Naoya Inoue and Terence Crawford.
Usyk's performance was so impressive that even Crawford acknowledged after the fight that Usyk deserved consideration as the best fighter in the world.
"Man yall better put some respect on [Usyk] man," Crawford wrote on X after the fight. "He definitely a candidate for #1 P4P fighter in the world. I'm no hater. He beat the man that beat the man in a bigger division, giving what he's already done. Salute brother!"
Usyk (22-0, 14 KOs) -- a former undisputed cruiserweight champion -- joins Crawford, Inoue, Katie Taylor and Claressa Shields as the only boxers to win undisputed championships in two divisions in the four-belt era.
"Usyk is the true definition of pound-for-pound," boxing analyst Timothy Bradley Jr. said about his decision to rank Usyk No. 1 on his list. "Outweighed by almost 40 pounds by Fury, with a reach disadvantage of seven inches and a height disparity of six inches, he even scored a knockdown of Fury. And let's not forget that he beat another giant, Anthony Joshua, not once but twice. What he accomplished Saturday night was truly remarkable."
Boxing writer Mike Coppinger agreed, moving Usyk from the No. 3 spot to the top of his list.
"You could place any of Usyk, Crawford or Inoue in the top slot, but the Ukrainian has epitomized what it means to be the pound-for-pound best following yet another win over an elite heavyweight who was far bigger. More so, Usyk came close to stopping Fury -- as well as Joshua -- and he has done this after dominating the cruiserweight division."
With the loss, Fury (34-1-1, 24 KOs) falls out of the top 10, making way for Teofimo Lopez Jr. to return.
