In 1963, La Rhodienne came into play to keep Racing Brussels' matricule n°6 alive. On June 21，1963，Racing Club changed its name to Royal F.C. La Rhodienne, keeping the matricule n°6. On the next day, K. Sport Sint-Genesius-Rode (matricule n°1274) changed its name to Royal Racing Club de Bruxelles. On June 23，the club wearing the matricule N°6, which had just been renamed to Royal FC La Rhodienne, now changed its name to K. Sport St-Genesius-Rode. The clubs had effectively changed names, so although the original Racing Club merged into R. Racing White in 1963, it was effectively the matricule n°1274 that merged, and the old matricule 6 was kept alive in a different club.
