Fisher cautions Joshua ahead of the fight with Dubois

Johnny Fisher (11-0, 10 KOs), who had the opportunity to spar with Daniel Dubois (21-2, 20 KOs), warns Anthony Joshua (28-3, 25 KOs) ahead of their September IBF heavyweight title fight.

"I think this fight will end in a knockout," the undefeated British heavyweight told Sky Sports. - Dubois will come into the ring charged up and put Joshua down. That's the way he fights. He's an aggressive boxer, although his aggression is calculated."

"I've sparred with Dubois many times and he's definitely the strongest puncher I've ever fought, he can really punch! Daniel takes no prisoners when sparring. You have to be on your guard because this is a shootout. However, we know how well Joshua is hitting towards the right. If Dubois opens up too much, Anthony will answer him like Ngannou. I know Dubois is on another level, but Joshua's right is deadly. The same way Charles Martin lost, Joshua has shown that many times. If I had to pick a winner, I'd lean slightly towards Joshua. He's more calculated, more experienced and that could play into his favor. However, if Dubois hits him cleanly in the jaw, the memories of the lost fight with Andy Ruiz may come back," said Johnny Fisher, who will step into the ring against Alen Babic (12-1, 11 KOs) this coming Saturday.
