The former international back rower has left Sheffield Eagles, and will now be the Academy head coach at London.
“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,” said Langley.
“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. From signing as a professional player at 16 years old, playing in Super League, winning Grand Finals and, most of all, representing my country at the highest level.
“A huge thank you to all the wonderful people I have met along the way, the players, coaches, back room staff and fans from each club that made the journey so memorable.
“And of course thank you to my parents, sister and Rosie for being with me through every run, tackle, injury, heartache and triumph!
“Thank you all. It’s been an incredible chapter in my life and now it’s time to move onto the next one.”
