[3] Selånger won ski jumping bronze medals at the 1931, 1933, and 1934 FIS Nordic World Ski Championships and a gold medal in the 1933 nordic combined event.

In 1939, Selånger became the first non-Norwegian to receive the Holmenkollen medal.

He competed in skiing as Sven Eriksson until the 1936 Winter Olympics, and then changed his surname to Selånger, after his hometown, to avoid being confused with numerous other Swedes named Eriksson.

In retirement he returned to bandy, as a player and coach for IK Viking, and worked as a sporting goods trader.
