The team says Pihos died early Tuesday at a nursing home in Winston-Salem, N.C., after a long battle with Alzheimer's disease.
Pihos was a member of the Philadelphia teams that captured consecutive championships starting in 1948. He made the game-winning catch in the 1949 game against the Rams.
Pihos finished his nine-year career with 373 catches for 6,519 yards and 61 touchdowns. He was inducted into the Pro Football Hall of Fame in 1970.
