Anthony Joshua could face British star next if he beats Oleksandr Usyk
Joshua could be set for a domestic dust-up if he comes through his next opponent in London.
Usyk will face Joshua following the collapse of Joshua-Fury and is the WBO's mandatory challenger.
Should Joshua come through his toughest test yet then an all-British clash could be next, and it may not be Tyson Fury.
Dubois or regular titlist Trevor Bryan are in the frame to seal a lucrative showdown against Joshua or Usyk. Joshua has already fought a mandatory challenger in Kubrat Pulev, dispatching him inside nine rounds at the SSE Arena, Wembley, in December.
Should he overcome Joshua, he'll become just the third fighter after Evander Holyfield and David Haye to unify the 200lbs division and win a world title at heavyweight.
Rematch clause added
Alexander Krassyuk spoke to Planet Sport ahead of the blockbuster September showdown and revealed Joshua has inserted a rematch clause.
