In one long spell with the Grecians, and a shorter one several seasons later, Jon Richardson made well over 300 league and cup appearances for Exeter City between 1994 and 2008. On his first departure from St James Park, Jon joined Oxford United and was to return to the club from Forest Green Rovers. 

Jon joined Exeter City as a trainee and, after making his debut in a 5-0 home defeat against Cambridge United in April 1994, agreed professional terms in July 1994. Establishing himself quickly, and impressing straight away, Jon went on to make over 250 league appearances for the Grecians over the next six seasons many of which were as club captain.

Making at least forty-five league and cup appearances for three consecutive seasons, up until the game at Swansea on 29 April 2002, Jon was a model of consistency before his transfer to Oxford United in August 2000 for a surprisingly nominal £5,000 fee. During his time with City he had contributed eleven goals from defence including seven in league games.

After two seasons, and around sixty first-team appearances, Jon left Oxford to drop into non-league and spend four seasons with Forest Green Rovers. Then, having not featured since the previous January, Jon left the Gloucestershire club in May 2006 and returned to Exeter City. 

City, now in their fourth season in the Conference, gave the 31-year-old Jon a first return appearance against Aldershot on 9 September 2006 as he went on to make twenty league and cup appearances including the home play-off semi-final against Oxford United. Having a similar number of outings during the following season, Jon’s final appearance for the club came in the FA Trophy defeat at Rushden & Diamonds on 12 January 2008.     

Jon then returned to the Midlands to embark on a physiotherapy degree and to continue playing at first for Worcester City and later Solihull Moors and Chasetown before retiring at the end of the 2011/12 season.
