Deontay Wilder and David Haye knocked me out, but none more than "Nigerian Nightmare".

BOXER Audley Harrison has revealed which opponent he faced had the hardest punch.

The 51-year-old was on the receiving end of four knockouts during his career and he gave a shock answer when choosing the hardest hitter he fought.

The Olympic Games gold medallist in 2000 has stepped into the ring with heavyweights like David Price, David Haye and Deontay Wilder.

But none of those three, including the Bronze Bomber, who is regarded to have one of the biggest punches, was the hardest Harrison has been hit by.

Instead, he surprisingly singled out a man nicknamed ‘The Nigerian Nightmare’.

Harrison told Mega Casino about coming up against him, saying: “I always say the hardest puncher I ever faced in my career was Samuel Peter – ‘The Nigerian Nightmare’.

“I boxed him in a pre-Olympic tournament, with a headguard on, he hit me on the top of the head and it sent shockwaves all the way through my body.

“The thing with David Price, I went to sleep when he knocked me out. When you’re knocked unconscious like that, you don’t know too much about it.

“Deontay hit me and then he threw 100 punches after that, so it was just all a blur.

“I just took the Samuel Peter shot and the headguard probably stopped me from getting knocked out.

But, I know that was the hardest shot I faced because it put me on Queer Street.

“The David Price and Michael Sprott knockouts put me to sleep.

I woke up and wanted to start fighting again, but my corner told me ‘Audley, the fight has been over for 30 seconds’.”

Peter held the WBC title in 2008 after beating Oleg Maskaev.

He then lost his belt to Vitali Klitschko later that year before losing to his younger brother Wladimir in 2010.

Peter ended his career with a 38-9 record with many of his losses coming towards the end of his time in the ring.

Hughie Fury, a relation to Tyson, Kubrat Pulev and Robert Helenius have all defeated him.
