Joe (King) Krol, a triple threat who won six Grey Cups in the 1940s and 1950s, has died. He was 89.

The Toronto Argonauts said Krol died Tuesday night in a Toronto hospital. Cause of death was unknown but the quarterback had been admitted after a fall in his apartment.

Krol, who could run, kick and pass, was one of his era's dominant players.

Born Feb. 20, 1919, the Hamilton native helped the University of Western Ontario to the intercollegiate title in 1939 before joining the Hamilton Wildcats in 1942 and winning the Grey Cup the next year.

He signed with the Argos in 1945, earning consecutive Grey Cup victories between 1945 and 1947. Krol, who with teammate Royal Copeland became known as the "Gold Dust Twins," also won Grey Cups with the Argos in 1950 and 1952.

Krol was voted Canada's male athlete of the year in 1946 and 1947 by the Canadian Press. He won the Jeff Russel Trophy as the Eastern Division's most outstanding player in 1946.

He was inducted into the Canadian Football Hall of Fame in 1963 and Canada's Sports Hall of Fame in 1975.

Krol's No. 55 jersey is one of only four in Argo franchise history to be retired and he was also named to the all-time Argos team in 1996.
