Frank (Pop) Ivy, the only man to coach in the CFL, AFL and NFL, passed away Wednesday.

He was 87.

Ivy coached the Edmonton Eskimos for four years, compiling a 50-14 record and winning three consecutive Grey Cup championships from 1954-56, all against Doug Walker and the Montreal Alouettes.

He played for the Pittsburgh Steelers and Chicago Cardinals before returning to the University of Oklahoma, his alma mater, as an assistant coach.

Ivy joined the Eskimos in 1954, then became head coach of the Cardinals in 1958, who relocated to St. Louis two years later.

But his success in Edmonton failed to carry over to the NFL.

Under Ivy, the Cardinals posted four losing campaigns and a 15-31-2 record overall.

Ivy eventually jumped to the Houston Oilers of the AFL in 1961, going 17-11 record in two seasons.

He later served as an assistant coach and scout with the New York Giants before retiring in 1984.
