He made just one appearance for Scotland, and scored twice in a 4–1 win against Ireland on 16 March 1912.
During the First World War he "guested" for Preston North End for several seasons. After retiring in 1918 he worked at management level in the Lancashire cotton industry, serving as chairman of a local firm in Blackburn for almost 40 years. He died at Cheadle Royal Hospital in Cheshire.
