A memorial ceremony will be held at San Diego State University today for former Chargers and Aztecs football head coach Don Coryell.

Coryell, who is credited with helping revolutionize football's passing game, died of pneumonia at the age of 85 on July 1 at Grossmont Hospital in La Mesa.

Scheduled to speak at the memorial ceremony, which gets under way at 2 p.m. at SDSU's Viejas Arena, are NFL Hall of Fame members Dan Fouts, John Madden and Joe Gibbs, along with SDSU and NFL alumni Fred Dryer and former Chargers and Aztecs assistant coach Jim Hanifan.

Organizers said long-time friends and those who knew Coryell best also will share their memories of the coaching legend.

Coryell coached the Chargers to a 72-60 record from 1978-86, including three American Football Conference West Division championships. He coached San Diego State to a 104-19-2 record from 1961-72, including NCAA College Division national championships in 1966, 1967 and 1968.

Coryell also coached the St. Louis Cardinals in 1973-77.

Coryell was inducted into the College Football Hall of Fame in 1999. He was the first coach to win 100 games at both the college and NFL levels.
