Huddersfield midfielder Dean Whitehead will retire after Sunday's final Premier League match against Arsenal and begin a coaching role at the club.
The 36-year-old has played over 600 matches for five professional clubs, including Oxford United, Sunderland, Stoke City, Middlesbrough and Huddersfield.
He will be part of David Wagner's technical staff from the start of next season, before taking charge of the club's new under-17 Academy age group in January 2019.
Whitehead joined Huddersfield from Middlesbrough in 2015, helping them win promotion to the Premier League last year.
He already holds the UEFA A coaching licence and will follow the path of club captain Mark Hudson who retired last season.
Huddersfield head coach Wagner said: "I'm so happy that Dean has decided to begin his coaching career at Huddersfield Town.
"Dean is a winner. He demands 100 per cent effort from himself and everyone around him, he commands respect and is top quality in everything he does.
"We will give him every experience of coaching and behind-the-scenes work with the first yeam during the first part of next season before he takes on his next challenge with the under-17 side."
