London Wasps forwards coach Trevor Woodman is to move on at the end of the season after four years at Adams Park.
Woodman joined the club in 2009 after beginning his coaching career in Australia following his retirement from playing.
He said: "I've had four really enjoyable years here and it's now time for me to seek a new challenge elsewhere.
"Working with lots of talented young players and helping them come through and emerge as key Premiership names has been something I have been very proud of.
"I have also learned a lot from Dai Young this season from his experience as a director of rugby.
"When Dai joined two years ago we mutually agreed I would stay on for two more years, while he assisted all coaching areas, and then he would take full control of the forwards, so it's now time for me to move on."
Dai Young added: "On behalf of everyone at Wasps I would like to say a big thanks to Trevor for all of his hard work and dedication over the past four seasons and wish him all the best in the future."
