Johnny Grainger was a Scottish association football inside forward who played professionally in the American Soccer League and Eastern Professional Soccer League.
In December 1922, Grainger signed with Bethlehem Steel.[1] Grainger remained with Bethlehem Steel through the 1927–28 season. In August 1928, Grainger and Bethlehem Steel could not agree on a contract and the team placed him on the transfer list.
