The PPV showdown has the young Brit, in his first-ever world title fight, facing off with the Ukrainian fighter in what is expected to be a cauldron of noise in Wroclaw, Poland.
Even the undercard is stacked with Ukraine’s best boxing talent for what should be a memorable night of boxing.
In the main event, Usyk is expected to dominate Dubois and continue on the pathway to a mouthwatering unification clash with Tyson Fury.
Dubois has won four fights in a row and a victory later today would be one of the shocks of this heavyweight generation.
