Pardee, 77, found out the cancer has also spread to other organs of his body. He now plans to move into a Denver hospice to live with his wife, Phyllis, who has been there getting care after suffering a stroke.
Pardee had a brilliant football career, starting in Texas A&M under the legendary Paul "Bear" Bryant. He was drafted into the NFL by the Los Angeles Rams in 1957 and became a star, playing there until 1970.
George Allen, who had coached Pardee on the Rams, brought him into Washington for the last two seasons of his career, which ended after a loss in Super Bowl VII to the undefeated Miami Dolphins.
Pardee made the All-Pro team in 1963 and 1971.
After his playing days were over, Pardee went on to coaching. He became head coach of the Chicago Bears, Washington Redskins and the Houston Oilers, where he had moderate success.
