William King Lyon (7 March 1912 – 5 December 1962) was a Scottish professional footballer, who played for Queens Park and Celtic.
Lyon began his senior career aged 21 with Queens Park after a spell with Kirkintilloch Rob Roy.
He was a centre-half in the era where that position was changing to an increasingly defensive role, and his attributes in that aspect saw him establish himself in the team ahead of other contenders.
[9][10][11] He was never selected for the full Scotland international team (he was ineligible under rules of the time due to his English birthplace),[4] but was a member of a SFA Touring XI squad which visited Canada and the US in 1939.
[13] Lyon served in the Scots Guards during World War II, rising to the rank of major and sustaining a leg injury in 1944 which ended his football career.
