Deontay Wilder dispatched Dominic Breazeale with a lightning-quick first round knockout to remain the WBC heavyweight champion.

With a steamroller right hand, the Bronze Bomber sent the title challenger crashing to the canvas at the Barclays Centre just two minutes and 17 seconds into the opener.

The devastating KO extended the 33-year-old’s unbeaten record to 41 wins and a draw from 42 bouts.

Wilder’s 20th first round knockout came after a rapid start to the bout in New York, the champion throwing an early right to set the tempo.

The energetic start exposed the Bomber to a shot by Breazeale as he came back off the ropes.

But the counterattack lasted seconds before Wilder, after a jab with the left, unleashed the decisive blow.

The right hand connected with Breazeale’s jaw and the challenger crumpled on the spot, lying spread eagle as Wilder danced around the ring.

Breazeale managed to get to his feet, but dizzily stumbled backwards into the ropes as the referee made it clear the fight was over.

Wilder’s last fight, a bout with Tyson Fury in December, ended in a controversial draw.

Many felt the American was fortunate to keep his unbeaten record intact following the fight.
