Stephen Jones, Wales's most capped player, will retire from rugby at the end of this season. The 35-year-old is to join the coaching staff at his current club Wasps.
The former Scarlets and Clermont Auvergne fly-half has scored more points for Wales than anyone apart from Neil Jenkins.
In addition to winning 104 Wales caps, he also made six Test appearances for the British and Irish Lions.
"I feel incredibly lucky to have played for some fantastic sides down the years," Jones said.
"And I feel the time is right for me now to make the transition into coaching, which is what I have always wanted to do.
"There is an opportunity for me to do that at London Wasps, and I am very excited about the next step of my career. I am taking with me some incredible memories and experiences."
The Wasps rugby director, David Young, has no doubt Jones will make a success of his new role. "I always thought Stephen would make an excellent coach, and everything I have seen of him this season backs that up," Young said. "What we are losing on the field we are gaining off it."
