John Ferrier played for Exeter City during 1956/57. He joined the club from Clyde at the same time as John Divers and later played for Yeovil Town

Hailing from Edinburgh, John started his professional career with Brighton and Hove Albion in October 1946 but after just one game and one goal, he returned to Scotland to play for  Ashfield. He then joined Clyde where, between 1953 and 1956, he made around a dozen league appearances.   

Turning down an offer from Walsall to sign for Exeter City, he made his Grecians debut in a 1-0 defeat at Norwich City in August 1956 and went on to play regularly in the left-back position until he broke his ankle in a game at Bournemouth in March 1957. 

Although he signed for Yeovil Town in the summer, John was forced to retire from football in November 1957.
