Prescot, Lancashire born inside forward Jack Lyon joined Second Division Hull City from local junior club Prescot in October 1913, making his Football League debut the same month at Leeds City, scoring 4 goals in 25 games that season. However he only played once more for Hull in January 1915 before the onset of the First World War intervened to force the suspension of peacetime football, but after the War Lyon resumed with them in 1919 scoring twice more in 13 further appearances for The Tigers in 1919-20.
In July 1920 he joined Leeds United for £300 but despite being a regular performer scoring three times in 33 appearances during their debut season and playing in their inaugural Football League fixture at Port Vale that August, he was released in the summer of 1921, returning to Prescot Cables. He returned to Football League action in the summer of 1923 with newly elected New Brighton, scoring 5 goals in 30 appearances during their inaugural 1923-24 Football League campaign and surely becoming one of only a handful of players to have played in the first Football League fixtures of two different clubs when he played at Bradford Park Avenue in August 1923. At the end of the season he returned to non league with Mold Town before re-joining Prescot Cables in 1926.
His older brother Sam Lyon also played for Prescot and Hull City, and also played for Barnsley. He was killed in action on the first day of the Battle of the Somme on 1st July 1916.
