Cooper played junior football with Mugiemoss before starting his professional career with Aberdeen in 1928. Cooper played almost 400 senior games for Aberdeen in a 20-year career which was temporarily halted by the Second World War in 1939. Two years after resuming his career, he played a large part in Aberdeen's 1947 Scottish Cup run but missed the final through injury. The Scottish Football Association gave Aberdeen permission to award him a winners' medal, despite him not playing. He represented the Scottish League XI twice, before the war.
