Kerr began his senior career with Hibernian in 1910, having previously played with junior sides Prestonpans FC, Wallyford Bluebell and Wemyss Athletic.
[1] Kerr was signed as a replacement for Scotland international fullback James Main, who died as a result of injuries sustained on the football pitch on Christmas Day 1909,[1] but played most of his career as a right half.
He was a mainstay of the side over the next 16 years,[2] helping Hibs to reach three Scottish Cup Finals, although on each occasion he ended up on the losing side: in 1914, Hibs drew the initial final 0–0 with Celtic but succumbed 4–1 in the replay at Ibrox; Celtic again proved too strong in 1923, while the following year Hughie Gallacher's Airdrie won 2–0.
In 1926, the then 34-year-old Kerr switched from the east side of Edinburgh to the west, joining Hibs' rivals Hearts.
He played one season for Leith, during which they suffered relegation from Division One, before retiring two months shy of his 41st birthday.
