Langley Park, County Durham born inside forward Harry Scott began his football career in north east junior football after the First World War with Bank Head Albion in 1919, playing for Newburn Grange in 1920 before returning to Bank Head Albion in 1921. He joined First Division Sunderland in January 1922 and made his Football League debut at Nottingham Forest more than 3 years later in March 1925, playing once more for Sunderland’s first eleven a week later against Bury at Roker Park, both games finishing 1-1 draws. He joined Second Division Wolverhampton Wanderers in June 1925 for £1,000, scoring 6 goals in 37 appearances before being signed by Hull City in November 1926.
His spell at The Tigers saw 10 goals in 34 appearances, before he was transferred to newly promoted Bradford Park Avenue in June 1928 in a player exchange, where he spent four seasons, albeit not always as a regular fixture in the first team. By the time he joined Swansea Town in July 1932 he had scored 21 goals in 77 appearances, and although he only had a single season at The Vetch Field, it proved by some distance the busiest of his career, as he scored 7 times in 41 appearances for The Swans. He joined Watford on a free transfer in July 1933 and played in their opening Third Division (South) fixture, a 2-1 home defeat to Cardiff City in August 1933, after which he was dropped and never made another first team appearance. He joined Nuneaton Town in July 1934 and went on to play for Vauxhall Motors in Luton after having amateur status granted in September 1935.
