Wales international Harry Robinson says he is "utterly devastated" after being forced to retire from rugby because of injury.
The 23-year-old Scarlets wing suffered a serious neck injury at the end of last season that required surgery.
Although surgery was successful, three times-capped Robinson has now confirmed his retirement following a lengthy battle to resume playing regional rugby.
"I am utterly devastated, and it is a very, very bitter pill to have to swallow," said Robinson, in a statement released by the Scarlets.
"During a game at the end of last season, I suffered a significant neck injury that subsequently needed serious neck surgery. It came as a huge shock to hear the surgeon explain that it was unlikely I would ever return to play professional rugby.
"This was not a prognosis that I wanted to believe or accept.
"Following successful surgery to ensure that I was at no greater risk of making my injury and condition worse, I was determined to come back to play again for the Scarlets. It is difficult to accept that I will never do this again.
"I have worked so hard over the last 10 months to return to full fitness and regain the functionality I had before the injury. It is with great regret that I have been unable to do this.
"As it has turned out, the consultant was correct with his initial assessment of my injury and the ultimate impact on my career.
"While I am devastated, I count myself very lucky and enormously privileged.
"I have had a fantastic six years as a professional rugby player with both Cardiff Blues and Scarlets. I have travelled all over the world at every age grade, with Wales sevens and the Wales squad.
"New challenges lie ahead of me now, and I will embrace these with the commitment and dedication I have learnt over the years as a player."
Robinson made his Wales debut against the Barbarians in 2012, scoring a try, then started both Tests on Wales' Japan tour a year later.
