The heavyweights collide for Dubois’ IBF heavyweight title at Wembley Stadium on Saturday night.
Dubois makes the first defence of his new title against a rejuvenated Anthony Joshua who is looking to become a three-time world champion.
Dubois surprised many by defeating Filip Hrgovic in June when he weathered an early storm and slowly took over the fight to stop the Croatian on cuts in Round 8.
Former world champion Richie Woodhall has warned Joshua about one of Dubois’ weapons in particular, his lethal jab.

This isn’t just a normal jab,” said Woodhall on a TNT Sports preview. “It’s probably as hard as a lot of heavyweights’ right hands. This is how hard this shot is.
“Daniel Dubois’ jab is the best jab in the heavyweight division today by far, his timing, his accuracy.
“Most of the time, the jab is used as a point scorer to set up the backhand. But Daniel’s jab, it’s a hurtful punch. It’s not just a point scorer.
“You’ve got to concentrate. It’s all about concentration. That’s why a very fast jab is a hard jab to defend against because you don’t know when it’s coming.
“If Daniel is going to win the fight, the jab is going to play a major role in him getting a victory, a major role, because it will set up all his other work.”
But despite this tool Woodhall believes Joshua will be too much for Dubois.
He concluded: “For me, I actually think AJ will win this fight, I am sorry to say for Daniel Dubois.
“I think he gets knocked out, and I think he gets knocked out mid-rounds.
