In 2015 as a teenager Daniel Dubois dropped Anthony Joshua at sparring.
Six years later he made his debut in the United States and showed the American audience just how much of a threat he can be in the heavyweight division.
Dubois (17-1) sent Joe Cusumano (19-4) to the canvas three times, earning a first-round TKO victory before the Jake Paul versus Tyson Woodley main event.

It was the first time Cusumano had been stopped in his professional career.
“My dad told me in the dressing room to go for the first round, so I went for the first round,” Dubois said post-fight.
Not everything has gone to plan for Dubois in the early stages of his career.
The 23-year-old lost his British, Commonwealth, WBC Silver and WBO International heavyweight belts in a knockout defeat to Joe Joyce last year.
Since then though he has won two straight and both by knockout.
“Dubois just detonated the bomb, welcome to America,” Mauro Ranallo said in commentary for Showtime Boxing.
“It is exactly the way Daniel Dubois dreamed of making his debut in the United States,” Brian Custer replied.

“As a 23-year-old he came off that very disappointing loss to Joe Joyce. He’s an exciting fighter, he has the power you need in the heavyweight division and he showed that tonight.”
A left hook and follow-up right hand had Cusumano in trouble early before Dubois went after him again with a ring hand and earned the first knockdown.
A jab set up the right hand and a later left hook to score the second.
The final decisive knockdown came with a series of right hands as Cusumano struggled to get anything going on the ropes.
