Lyndon Duncan made a single appearance for City in a FL Trophy game after signing from QPR in 2003.

Lyndon had signed as a full professional with Queen’s Park Rangers in August 2001 having been a trainee at the club. Whilst at the Loftus Road club he played for England at under-18 level and appeared in a pre-season first-team friendly against Celtic.

After signing for Exeter in October 2003, Lyndon quickly made his debut against Hereford United in the FL Trophy on 21 October 2003. It proved to be his only appearance in senior football. 

After leaving the Grecians later that season Lyndon joined Wealdstone close to his home in the Wembley area. He later went into the construction industry and, in 2023, was working for Tarmac on the HS2 project.
