Oleksandr Usyk wants to 'push the boundaries of the sport' | Rico Verhoeven 'not an easy opponent at all,' says promoter

Until the fight was made no one expected Oleksandr Usyk to fight Rico Verhoeven.

Now on Saturday, boxing's imperious unified heavyweight champion Usyk will fight kickboxing superstar Verhoeven in Giza, Egypt.

It will be a boxing bout, so Verhoeven is venturing into Usyk's world. But the Ukrainian's team insist they are taking him seriously as a challenger.
