Hall of Fame NFL offensive lineman Mike McCormack, who helped bring the Carolina Panthers into existence, died Friday at the age of 83, the Panthers confirmed.
McCormack was inducted to the Hall of Fame in 1984 after helping the Cleveland Browns win two NFL titles. He was named to the NFL's 75th anniversary all-time team.
McCormack was head coach of the Philadelphia Eagles from 1973 to 1975, and later joined the Seattle Seahawks as their president and general manager.
With the Panthers, McCormack served as a consultant to owner Jerry Richardson through the expansion process, and was later named the Panthers' first president.
