Worcesters centre Ben Hinshelwood has announced his retirement from professional rugby with immediate effect.
Hinshelwood, 28, who won 19 caps for Scotland, has been plagued by a long-standing back problem.
Two months ago, the condition led him to announce he was taking a break from international rugby but, after further medical advice, he has now called time on his career completely.
"This is very sad news for everyone connected with the club," said Worcester rugby director John Brain.
"Ben has been a key contributor to what we have achieved so far at Worcester, and I would like to place on record my thanks for everything he has done for us, both on and off the pitch.
"However, we fully respect and support his decision, as his long-term health has to be his primary concern.
"We all wish him every success for the future."
