John Harbin has signed a three-year contract to become part of manager John Sheridan's back-room staff at Plymouth Argyle.
Harbin, 65, has previously worked as a fitness coach and a sports psychologist at Oldham Athletic, Crystal Palace, Charlton Athletic, Queen's Park Rangers and Coventry City.
Sheridan was a player at Oldham when Harbin was employed by the Latics' boss at the time, Iain Dowie, back in 2002.
Harbin was born in North Yorkshire but his family emigrated to Queensland, Australia, when he was young. He returned to England and coached rugby league clubs Wakefield Wildcats and Oldham Roughyeds before changing sports and teaming up with Dowie.
Harbin played a prominent role as Dowie led Crystal Palace to promotion to the Premier League in 2004. He also worked for Dowie at Charlton, QPR and Coventry, as well as Swansea City, before returning to Australia in 2009. Until late 2012, he was the coach of Central Queensland Capras, a semi-professional rugby league side.
A report in the Queensland-based Rockhampton Morning Bulletin has revealed Harbin's appointment, which has not been confirmed by the Home Park club yet.
Gus Poyet has confirmed he plans to lodge an appeal against being sacked by Brighton and Hove Albion, following the club's internal disciplinary hearing.
