London - Scarlets' Welsh wing Harry Robinson announced on Thursday a neck injury has forced his early retirement.
The 23-year-old suffered a serious neck injury at the end of last season that required surgery.
Although the operation 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 his club.
"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."
He added: "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.
