The ordering process for Ultimate Fighting Championship pay-per-views has changed: UFC 243 is only available on ESPN+ in the U.S.
Israel Adesanya will step inside the Octagon for the most significant fight of his career when he challenges Robert Whittaker for the undisputed Ultimate Fighting Championship middleweight title in the UFC 243 headliner on Saturday in Melbourne, Australia.

The two participants are at the height of their primes, have ties to Oceania and have not fought anyone with the kind of skills the other brings to the table.
