Mickey Murray played just one game in the NHL with the Montreal Canadiens on February 25, 1930, replacing George Hainsworth who was out with an injury.
Prior to getting his one-day of glory, Murray played many years in the minors. He played four years in Peterborough, two with the juniors and two with the senior club before moving on to the North Toronto Rangers and the Galt Terriers of the OHA Senior A.
Nearing the age of 30, Murray made the jump to the Can-Am league in 1927, signing on with the Providence Reds. It was while in Providence that Murray was promoted for one game with the Canadiens as an injury replacement, the result being a 4-2 loss to the New York Americans.
The final six years of his pro hockey career was spent in the AHA with St. Louis, Kansas City and St. Paul.
