Dwayne Peel has quit rugby with immediate effect on medical advice.
The 34-year-old, who won 76 caps for Wales, has made 20 appearances for Bristol Rugby this term.
However, having struggled to recover from a persistent shoulder problem, Peel has decided to call time on his career and join the coaching staff at Ashton Gate.
"It was a tough decision to make because I love the game. However, following the medical advice I really had no further choice," the scrum-half said in a statement.
"I've been fortunate enough to enjoy some incredible experiences during my playing career and have met some fantastic people.
"I'm grateful to Bristol Rugby for their support and will continue to work hard alongside the coaching team to ensure the season ends on a high. I am excited for the new challenge that awaits."
Peel also made three appearances for the British and Irish Lions.
