Daniel Dubois wiped out Trevor Bryan in the fourth round to take the WBA "regular" heavyweight title over in Miami, Florida.

Just 24, Dubois was in charge right from the first bell and the previously unbeaten Bryan offered up little in return fire. The Londoner did not rush his work and Bryan was first obviously rocked in the third by a flurry of heavy shots and it was a left hook in the fourth that floored Bryan and rendered him unable to continue.

"Now we can make some massive fights for the future," said Dubois immediately afterwards. "Bring them all on, now I am ready and I will become a better fighter from this. In my mind I was the favorite, no disrespect to anyone but Trevor's 0 had to go."

Dubois will now be made mandatory for a shot at the winner of the forthcoming Oleksandr Usyk-Anthony Joshua rematch, which is likely to take place on August 20 in Saudi Arabia.

In the meantime, Dubois would love to face a top contender like Dillian Whyte or Joseph Parker.

"The only words are 'and the new' and I am just so glad it is now. It is happening now and we have made it real, my dad and my family, I've done everyone proud, the country and I can't wait. In the first round I was just trying to figure him out and see what he had. I said I was going to test the chin and I just went for it," Dubois said.

"He brought out something in me, he brought out a wicked left hand! It was a punch-perfect ending and I am just so happy. I had a few rough patches during this camp, but we pulled through and we got the victory. I am just so happy to have got this world title. This is what all the hard work was for and, no disrespect to Trevor, but his 0 had to go and I was just in there on a demolition mission.

"I am ready for whoever is next. I believe this will instantly make me a better fighter now. When you win the world title they say you become next level so names like Dillian Whyte and Joseph Parker are all on my hitlist. I will fight whoever Frank puts me in with next. It has been amazing. Coming out here and winning a world title is what I dreamed of as a little kid and now it has finally happened."
