Jepson was born in Glasshoughton, near Castleford in West Yorkshire and after leaving school worked in the coal mines, playing football with Frickley Colliery in the Midland League.
7, Jepson had to content himself with a year in the reserves as Huddersfield again finished the season as League runners-up, coupled with a trip to Wembley for the 1928 FA Cup final, where they were defeated 3–1 by Blackburn Rovers.
In August 1928, Jepson was one of seven new signings as Southampton's manager Arthur Chadwick started to re-build a side that had finished a disappointing 17th in the Second Division in the previous season.
[8] With no offers at this fee and the club struggling with increasing levels of debt,[1] he was given a free transfer to Fulham in June 1932 (together with fellow forwards Bill Fraser and Arthur Haddleton) having made 95 appearances for the Saints, scoring 18 goals.
[8] During World War II, he guested for Port Vale and Swansea Town, and in 1948, now aged 45, he was granted a special permit to join Sussex League side Hove as their player-coach.
