He died Monday night at his home in Paoli, Pa., the NFL said Tuesday.
Marion might be best known for a controversial call he made on the Steelers game-clinching drive in Super Bowl IX. Larry Brown caught a 30-yard pass and fumbled the ball when he was thrown to the ground. The other officials on the field said the play was a fumble but Marion had the clearest view and correctly ruled it down by contact.
Marion was a former executive director of the NFL officials association. He was in the league from 1960-87 and worked playoff games in 20 consecutive seasons. He officiated in the 1971, 1975 and 1977 Super Bowls.
He is survived by his wife, Naomi, and four daughters.
