The victor will either fight the great Oleksandr Usyk for the undisputed world title, or the Ukrainian will have to give up his WBO crown, meaning Parker or Wardley would become the new WBO world champion.

As a former world champion himself, the more experienced Parker will enter as the narrow favourite - but when his younger rival comes to town, anything is possible inside the ring with unrivalled knockout power.
