Frank Warren explained how Dubois will beat Hrgovic: He did it last time against Miller.

Warren believes that if Dubois against Hrgovic looks like he did against Miller, he will win the fight.

Hrgovic is not Miller and he doesn't move around the ring like a punching bag in shorts and hardly throws a punch, it will be a completely different fight and Hrgovic will make sure that Dubois quits on his knee...
