Jason Leonard, international rugby's most capped player, will quit the sport at the end of the English Premiership season.
The Harlequins and former England prop, who announced the end of his international career in March after winning 114 caps, has turned down a one-year contract to continue his 14-year stay at the club.
Leonard said: "This decision has been a very hard one to make. I wanted to go out while I am still playing good rugby."
Leonard's last match for Quins will be the Parker Pen Challenge Cup final against Montferrand on May 22, but he is doubtful because of a foot injury.
Leonard added: "I still love the game and will miss the dressing-room banter and training sessions enormously.
"And a final with Quins would be a great way to finish my playing association with the club I have been with for 14 years.
"My family have had to put up with a lot of absences on my part over the years and the time has come to devote more of my time to them.
"I would like to thank the countless people who have helped me over the years and hope to be able to continue being involved in the game in some capacity," Leonard told BBC Sport Online.
After deciding to quit the club game the 35-year-old is due to play for the Barbarians against England on May 30 at Twickenham.
After that Leonard's final game will be at Cardiff's Millennium Stadium where a Jason Leonard XV will face a team put together by former Welsh international Neil Jenkins.
Leonard has already been tipped for a future role in England's coaching set-up by international boss Sir Clive Woodward.
At the time of Leonard's international retirement Woodward said: "When Jason decides to retire from club rugby I would like him to consider a coaching role within the game and hopefully at the RFU. He has a lot to offer and his experience would be invaluable."
