Worcester's former England scrum-half Shaun Perry has been forced to retire because of a knee injury.
The Warriors have announced that 34-year-old Perry has not recovered from an injury he suffered earlier this season and will step down from playing with immediate effect. He won 14 caps for England and was a member of the 2007 World Cup squad, while his club career also included spells with Bristol and Brive.
"Unfortunately, following the injury to my knee earlier this season it has not been possible for me to return to full fitness despite the best efforts of myself and the Warriors' medical team," Perry said.
"Specialist opinion is that I cannot continue a career in professional rugby.
"It is extremely hard to accept the decision that I must retire because, having started playing at the age of seven, rugby has always been a big part of my life.
"I very much hope to continue to be involved in rugby in some capacity."
