Leeds defender Leigh Bromby has announced his retirement but he is to remain at Elland Road as the club's Under-16 coach.
Bromby has not played since suffering a serious knee injury during the Whites' Championship clash with Cardiff in April 2012.
The 33-year-old told the club's official website: "I've been advised by the surgeon Andrew Williams to retire from the game. It's become clear over the last 14 months that I wouldn't be able to continue in a playing capacity and it's with a heavy heart that I've decided to formally retire as a player.
"People say as one door closes another opens and I'd like to thank Leeds United for giving me the opportunity to take my first steps in coaching with the Under-16s.
"The club were good enough to allow me to gain experience last season by working with young players and I'm delighted to have the opportunity to continue that work on a full-time basis now.
"I've had a wonderful career and played for some wonderful clubs and I wanted to finish at a club I've always supported.
"I'd like to thank the physios at Leeds, Harvey Sharman and Paul Perkins in particular, for their hard work and support during what was a tough year, and of course, a big thank you to my family who have supported me throughout my whole career and helped me achieve my dreams."
Bromby began his career at Sheffield Wednesday. He made over 100 appearances for the Owls before moving across the Steel City to join Sheffield United, where he won promotion to the Premier League in 2007. He played 66 times for Leeds, scoring one goal, and was a promotion winner with the club in 2010.
The defender added: "My personal highlights were winning promotion with Sheffield United and winning promotion with Leeds. The aim when I came to Leeds was to win promotion back to the Premier League and I hope that can still be achieved while I'm at the club."
