Sheffield Eagles forward Jamie Langley is to join the coaching staff of London Broncos after calling time on his 15-year professional playing career.
The 31-year-old former Bradford and England loose forward won the Challenge Cup, Super League Grand Final and World Club Challenge during his time with the Bulls from 2002-13 and was a member of England's 2008 World Cup team.
He left Odsal to join Hull KR in 2014 and spent the 2015 season in the Championship with Sheffield Eagles.
Langley, who will coach London's academy team at their new Ealing home in 2016, said: "It is with a heavy heart that I officially announce my retirement from the game that I have played and loved since I was a young lad starting out at Normanton Knights almost 26 years ago.
"I have dedicated myself to the great game of rugby league for over 15 seasons as a professional and, although I still have a burning desire to play the game, I am no longer physically capable of attaining the standards I have always set for myself. It's time to put the horse out to pasture.
"There have been some unforgettable experiences along the journey and I'm truly grateful to say that I have achieved every goal I set out for myself as a young lad."
A Sheffield spokesman said: "Everyone at Sheffield Eagles would like to thank Jamie for his service and wish him the best of luck in his new role at London Broncos."
