Born in Stepney, Geidmintis made his Football League debut for Workington on 3 April 1965, aged just 15 years 247 days. Geidmintis also played in the Football League for Watford, Northampton Town and Halifax Town, before returning in 1980 to a Workington side which had dropped into non-league football. He retired in the 1980–81 season, aged 31, due to a heart condition that contributed to his death 12 years later.
