"Our deepest sympathies go out to Red's entire family, especially his wife, Nan," Broncos President and CEO Joe Ellis said in a statement. "Red was a beloved member of the Broncos' family. He left a great impact on this franchise by laying the foundation for our championship tradition and was so proud to be part of our first Super Bowl team 40 years ago.
"You could tell how much the Broncos meant to Red, and he's meant so much to everyone here. Red was overjoyed to get that phone call in May notifying him of his Ring of Fame selection, and we're all very saddened that he won't be able to join us when we honor him in November."
Miller's accomplishments with the Broncos will be honored by the team on Nov. 19 during Denver's alumni weekend. His bronze pillar will be unveiled at Sports Authority Field at Mile High's Ring of Fame Plaza on Nov. 17 and his name will be revealed in the stadium's Ring of Fame at the Nov. 19 game against the Cincinnati Bengals.
Miller compiled a 40-22 record as head coach of the Broncos from 1977-80. Miller was named 1977 NFL Coach of the Year after guiding the team to the AFC title. He also was at the helm during the Broncos' infamous Orange Crush defense era -- a unit that allowed a league-low 15 points per game from 1977-80.
