Gary Marshall, who started his career with Bristol City, made sixty appearances for Exeter City during the early-1990s at the end of his professional career. Signed from Scunthorpe United, he had also appeared for Torquay United (on loan) and Carlisle United. 

Gary had first attracted the attention of Exeter City when, as a teenager, he was playing for Shepton Mallet. Turning down the opportunity of an apprenticeship with the Grecians, he concentrated on becoming a cabinet maker before signing for Bristol City as a nineteen-year-old in 1983. Having had a short period on loan at Torquay in December 1984, Gary went on to play in 68 league games (7 goals) for the Ashton Gate club before moving to Carlisle United in July 1988 and on to Scunthorpe United in July 1989 for a fee of £50,000. 

After playing 41 league times for Scunthorpe, the 26-year-old Gary joined newly-promoted Exeter City in October 1990 in a £25,000 deal. Appearing first against Tranmere Rovers on 20 October 1990, Gary helped Exeter stabilise in the third-term with a 16th place-finish and remained with the club during 1991/92 as the club slipped to 20th place. Starting 48 league games - and coming on a dozen times as substitute - Gary scored three times in each of his two seasons before leaving St James’ Park in May 1992. 

Finishing on 197 league games for his various clubs, Gary signed for Clevedon Town in the summer of 1992.
