Career
Foster came through the ranks at Mansfield, and made his debut on 4 September 1971 against Plymouth Argyle, in the same game that his unrelated namesake Barry Foster also made his debut. Due to sharing the same name and being similar in appearance, the two were often assumed to be brothers. During the 1976-1977 campaign, Foster also scored a career-best nine goals.
In 1979, after nine years at Field Mill, Foster moved to Peterborough United for a £13,000 transfer fee.
In total, he played 241 first-team games for Mansfield and scored 19 goals. His spell at Peterborough lasted two years, and he later wound down his career with spells at non-league clubs Grantham Town, King"s Lynn and Corby Town, where he was player-manager.
After his retirement from the game, Colin settled in the Peterborough area, where he works as a painter and decorator.
