Harold Roy Killin (born 18 July 1929), known as Roy Killin, is a former professional footballer who played as a full back in the Football League for Manchester United and Lincoln City.
[3] In the 1953–54 season, he played ten games (seven in the League) for Second Division side Lincoln City.
Killin began playing for non-league Peterborough United in 1954 and made 101 first team games.
His playing career was cut short due to an injury in 1958 when the doctor told Killin that continued treatment could cause permanent damage to his right knee and therefore suggested a complete rest from playing for an extended period of time.
In 1962, Killin moved with his family to Toronto, Canada and played two more years as a semi-pro in the National League before retiring as a professional in 1964.
