Decker and his brother Rolf where born in Germany, but grew up in England. In March 1939, the Decker's parents, Ilse and Hans, sent the two boys to England as part of the kindertransport. He attended the Royal Grammar School, High Wycombe, England from 1948 to 1950 after transferring from Wycombe Technical Institute in 1948. While at RGS, he played both soccer and cricket, as the wicket keeper.
After graduating from RGS, Decker signed with Wycombe Wanderers before moving to the United States in 1950. He moved to the U.S., along with his brother Rolf Decker to rejoin their mother who lived there. When he arrived in the U.S. he joined New York Hakoah of the American Soccer League (ASL).
Decker earned his lone cap as a second half substitute in the only U.S. game of 1953, a 6-3 loss to England. Decker came on at halftime and scored in the 59th and 67th minutes. Despite such a productive start to his national team career, he was never called into the U.S. team again.
