Daniel Dubois sent one final terrifying message to 2020’s heavyweight world champions,Deintay Wilder and Anthony Joshua: ‘I am coming for you’.

The 22-year-old Greenwich starlet destroyed Japanese hardman Kyotaro Fujimoto in round two of their Copper Box clash, with one of the most devastating single punches of the year.

That means the Peacock Gym prodigy ends 2019 well up the rankings of the WBA, WBO and WBC and close to world title shot.

Once Tyson Fury and Deontay Wilder settle their differences with two more fights to complete their trilogy in February and the summer – and Anthony Joshua handles his two mandatories – Dynamite Dubois will be blowing down their door.

Dubois said: “After the first couple of shots, I thought I would pace myself.

“I knew I had the power, I was confident about what I was going to do.

“I landed a sweet shot, and that was goodnight.

“If I keep collecting these nice belts, I won’t be too far from a world title shot, I just have to walk the path.

A vicious lead left-hook was Joe Frazieresque and an assault to the body would have folded a weaker man.

Fujimoto stood tall and left himself open to a sickening right hand that collapsed him entirely.

The medics dived into the ring before the referee even officially called off the fight and Dubois’ worried trainer Martin Bowers pushed his star pupil back into the corner to calm the celebrations, as their latest victim lay stricken and needing oxygen.

Thankfully the dazed and confused fighter rose to his feet and left of his own accord, unlikely to fancy returning in a hurry.
