A few weeks later on 2 July, during the 1972 French Grand Prix at Clermont-Ferrand, a stone thrown up by Emerson Fittipaldi's Lotus pierced Marko's helmet visor, permanently blinding his left eye and ending his racing career.
Algunhas semanas despois, o 2 de xullo, durante o Gran Premio de Francia de 1972 en Clermont-Ferrand, unha pedra lanzada polo Lotus de Emerson Fittipaldi perforou a viseira do casco de Marko, cegandolle o ollo esquerdo permanentemente e rematando a súa andaina nas carreiras.
