Harlequins prop Adam Jones has announced he will retire at the end of the season and move into coaching.
The 37-year-old former British and Irish Lion and Wales star will become Harlequins' assistant forwards coach next season, working alongside forwards coach Graham Rowntree.
It will bring an end to a glittering playing for Jones, who won four Six Nations titles and three Grand Slams with Wales - while being capped 95 times - and toured with the Lions in 2009 and 2013.
Jones said: "I'll be officially retiring from playing at the end of the season. I've had a great career and never thought I'd go on to achieve what I have.
"I'm so passionately proud to have played so many times for Wales and was fortunate to be a part of three Grand Slam-winning teams.
"But it's time to move onto the next chapter of my career and concentrate on coaching. Coaching is a route I have always wanted to go down, so this is an opportunity for me to work with and learn from two of the best in John Kingston and Graham Rowntree.
"We potentially have the best group of props in the Premiership at Harlequins, with England props Joe Marler, Kyle Sinckler and Will Collier, plus the up-and-coming Lewis Boyce. So I hope to be able to help them push on with Harlequins and at International level."
