The former San Diego Chargers player was a three time Pro-Bowler who rushed for 6,702 yards and scored 71 touchdowns in a 110-game career.
Muncie was drafted by the Saints as the third overall pick in the 1976 draft when he was 23 years old. He became the first Saints player to go to the Pro-Bowl, where he ended up earning MVP honors.
Muncie was famously suspended after Week 1 in 1984 after he tested positive for cocaine. He was then traded to the Minnesota Vikings in 1985 after being reinstated, but never played another NFL game.
