In the first match, played at Estadio Centenario in Montevideo, River Plate won 2–1 but the second leg, to be held in Buenos Aires, was never played. As the associations did not decide about the issue, no title was awarded."Copas Interligas 1947" by José Carluccio, 14 July 2009[https://www.clarin.com/futbol/trece_decadas-1916-1927-1937-1959-copas_oficiales-aldao-barnade_0_HyjYvVYD7x.html Las copas de River y el valor de la letra oficial] by Oscar Barnade on Clarín, 18 Aug 2015
