Attercliffe, Sheffield born left back Stephen Fagan joined Rawmarsh Athletic in 1907 before spending 1908-09 on the books of hometown professional club Sheffield United, without making their first eleven. In 1909 he moved to Southern League Plymouth Argyle with the club handbook stating: ‘Fagan has youth on his side, is regarded as a back of exceptional promise, and in securing his signature Argyle may be said to have brought off one of the greatest captures by Southern clubs this season’.
However, after just 15 appearances at full back during the 1909-10 campaign, Fagan left Argyle to join First Division Bristol City, where he made his Football League debut against Manchester United in October 1910. He spent two seasons at Ashton Gate, they were relegated in his first, playing 34 times for the club before signing for Stockport County in the 1912 close season. Over the next three years he appeared in 114 matches for The Hatters, being ever present in their 1913-14 campaign, before the First World War ended his playing career.
