Cox recorded a victory in his NHL debut with the Montreal Maroons surrendering just two goals. Three full seasons would pass before opportunity would knock again.

While playing for the Detroit Olympics of the International-American Hockey League in 1933-34 he was loaned to the New York Americans to sub for an injured Roy Worters. Later that season he made two appearances for the Detroit Red Wings to replace John Ross Roach who was unable to play. His final NHL appearance came on February 16th, 1936 when Montreal Canadiens netminder Wilf Cude went down Cox suited up for a game against the New York Rangers. Cox held Les Habitants in the game allowing just one goal and helped them earn a 1-1 tie.

The next year, 1936-37, was Cox's last as a hockey player. After playing 10 games with the Kansas City Greyhounds in which he was unable to record a victory he hung up his goalpads for good.
