The legendary sportscaster and Hall of Fame football coach John Madden died “unexpectedly” Tuesday morning, according to the NFL. He was 85 years old.

Madden has been a household name for football fans since the late 1970s, whether as a coach, an NFL broadcaster, or the face of a successful video game franchise.

Madden turned to coaching after being injured as a rookie with the Philadelphia Eagles. He began as an assistant coach at Allan Hancock College in 1960 and rose to become the program’s head coach in 1962. From 1964 to 1966, he was the defensive coordinator at San Diego State University before returning to the NFL as a linebackers coach for the Raiders, who were based in Oakland at the time.

He took over as head coach in 1969 and led the Raiders to Super Bowl XI victory in 1977, defeating the Minnesota Vikings 32-14. Madden announced his retirement from coaching in 1979, citing poor health. He never had a losing season with the Raiders and is still the winningest coach in franchise history. In 2006, he was inducted into the Pro Football Hall of Fame.

Madden then transitioned to broadcasting, beginning as a color commentator for CBS in 1979. Throughout his career, he worked for the other three major broadcast TV networks, and he was a color commentator for both “Monday Night Football” and “Sunday Night Football” at various times. He was known for his in-depth commentary and colorful personality, and he left the booth at the end of the 2008 season.

Beginning in 1988, his voice, personality, and name were the foundation of the “Madden NFL” series of football video games, helping him become one of the sport’s most recognizable names for younger generations of football fans.

Madden cemented his status as a cultural icon outside of the NFL by appearing in advertisements and lending his voice to a variety of products, retailers, movies, and other endeavors.

Following the announcement of Madden’s death, tributes poured in. NFL Commissioner Roger Goodell expressed sympathy to Madden’s family.

“We all know him as the Oakland Raiders’ Hall of Fame coach and broadcaster who worked for every major network, but more than anything, he was a devoted husband, father, and grandfather,” Goodell said in a statement Tuesday.

“Nobody cared more about football than Coach. He represented football. He was a fantastic sounding board for me and many others,” he continued. “There will never be another John Madden, and we will forever be indebted to him for all he did to make football and the NFL what it is today.”

Jerry Jones, the owner of the Dallas Cowboys, called Madden’s death “a loss as great as the legacy John Madden created.”

“I am not aware of anyone who has had a greater impact on the National Football League than John Madden, and I am not aware of anyone who loved the game more than John Madden,” Jones said in a statement.

Former New England Patriots wide receiver Julian Edelman also praised Madden.

“When you think of NFL football, you immediately think of John Madden. Sadly, a Legend has passed away “He tweeted about it.

Dez Bryant, a former Cowboys wide receiver, attributed his love of the game to Madden. “Rest In Peace, John Madden… one of the main reasons I love football so much… wow!” he tweeted.
