Peter McGrail suffers brutal one-punch knockout as unbeaten runs comes to a crushing end

Peter McGrail was brutally knocked out by Ja'Rico O'Quinn in a major upset in Arizona on Saturday night.

On the undercard of Jesse 'Bam' Rodriguez's win over Sunny Edwards, the former Team GB amateur star suffered his first defeat in the professional ranks. The 27-year-old, who trains with Paul Stevenson at the Everton Red Triangle gym, was looking to cap a year to remember with a victory at the Desert Diamond Arena.

And McGrail looked well on his way to doing so as he outboxed O’Quinn from the first bell, and during round two he knocked down the 28-year-old, although replays suggested it was more of a slip. McGrail continued to dominate, and during round number four, he sent O’Quinn flying to the canvas after catching him with a short left hand.

However, the momentum of the fight took a dramatic turn with less than a minute left in round number five. Backed into the corner, O’Quinn unleashed a sweeping right cross that landed on the chin of McGrail, dropping him to the canvas.

“I said to him after it was hard to say that he didn’t switch off; it was almost like a freak shot. He was dominating the fight and looked fantastic, but he just got hit with a huge right hand."

Hearn also confirmed after the fight that a rematch clause was inserted into the contract and that he plans to stage the bout in the UK.

He said: “At
