I actually wouldn’t be surprised if this claim were true. But that’s only a portion of the story. Khabib Nurmagomedov may be the highest paid fighter in the sport right now. That would only be true simply because of the timing of his contract extension with the UFC.
ESPN and the UFC made their surprise announcement about the pay-per-view structure not even three months ago and many of the promotion’s biggest stars haven’t fought yet under the new deal. Conor McGregor has yet to iron out the details of his return.
