OLYMPIC boxing silver medal holder Fred Evans could be jailed after he pleaded guilty to a jaw-breaking punch that landed a friend in hospital for four days.

Evans, 24, who had his career guided at St Joseph’s gym in Newport since he was a youngster, pleaded guilty at Gloucester Crown Court yesterday to unlawfully wounding cage fighter Michael Wilson by punching him when they were both drinking at a Gloucestershire pub.

Prosecutor Julian Kesner said the injury had been caused by a single punch

Evans, of Oaktree Stables, Tyla Lane, Cardiff, is the current Olympic silver medal holder at welterweight after he was runner up at the 2012 Olympics.

Yesterday, he and his brother Jason, 22, of the same address were to have stood jury trial – Fred on a charge of wounding Mr Wilson with intent to cause him grievous bodily harm and both brothers on a charge of blackmailing Mr Wilson by demanding £5,000 from him with menaces.

The charges followed a confrontation at The Inn, Redmarley, near Newent, in last October, last year after the men had been drinking together for several hours.

After behind-the-scenes negotiations between prosecution and defence at court, the blackmail charge against both brothers was dropped and Fred’s plea to a lesser charge of unlawful wounding was accepted.

Judge Jamie Tabor QC ordered a pre-sentence report on Fred Evans and bailed him till October 12. Jason was discharged.

But before adjourning, The judge asked for victim Mr Wilson to be brought into court – a move welcomed by Fred’s barrister Ian Dixey, who said he was anxious for the court to see the difference in size between the two men.

“I think it is important you see Mr Wilson’s size in relation to the defendant,” said Mr Dixey, who said told the judge he would be asking for some video clips to be shown to the court at the next hearing

In the witness box, Mr Wilson was asked by the judge how he is now feeling and whether his injuries still cause him any problems, almost a year on from the assault.

“You had a broken jaw and your nose displaced?” said the judge.

Mr Wilson said: “I am shook up still. But I am physically OK now. I am a bit frightened and nervous. Everywhere I go I keep watching my back and looking over my shoulder.”

Prosecutor Julian Kesner said the injury had been caused by a single punch from Fred to Mr Wilson although there had been a flurry of further follow up punches from him, Mr Dixey told the judge he would be asking for some video clips to be shown to the court at the next hearing.

“They show Mr Wilson and my client having a good time together,” he said. “You are aware, of course, that they were in the pub for many, many hours before this happened. You can see the two of them together and you can see the different in size between the two of them.”

The judge told Evans that the adjournment for a pre-sentence report should not to get his hopes up that he will avoid jail.
