Song's next tournament was the 2003 Confederations Cup. The "Indomitable Lions" qualified for the semi-finals after wins against Brazil (0–1) and Turkey (1–0) and a draw with the United States. The defender then led his team against Colombia in the knockout stage. In the 72nd minute of the game, Song's long-time friend Marc-Vivien Foé collapsed in the centre circle, with no other players near him. Foé died the same day due to hypertrophic cardiomyopathy, a hereditary condition known to increase the risk of sudden death during physical exercise. Cameroon eventually won the game 1–0, but lost to France in the finals after extra time.
