LONDON -- Promoter Frank Warren has said Daniel Dubois needs to develop a mentality like Oleksandr Usyk following his knockout defeat to the Ukrainian on Saturday.
Dubois was floored with a huge right hand in Round 5 before Usyk finished the job moments later with a clean left that sent Dubois' mouth guard flying as he fell to the canvas.
Usyk left Wembley Stadium as a three-time undisputed champion while Dubois suffered his third career knockout defeat and second at the hands of Usyk.
Dubois, 27, has plenty of years ahead of him but Warren said he needs to learn from the defeat and improve his mentality.
"[Usyk has] got the most unbelievable mental attitude," Warren said. "That's what makes him, that's what Daniel's got to learn from this fight, try and get and develop the mental attitude that Usyk has.
"You've got to stick to the task, and he got careless and he dropped his hands, he got careless and he paid the price."

Asked if he thinks Dubois has more to give, Warren said: "We'll find out. He's only a young man.
"It's not like he took a belting, as we say in the business. He got knocked down twice and that was it.
"It's all about resilience. It's all about desire and wanting to be the best and more importantly learning from your mistakes. And that's what good fighters do."
