UPDATE 5:35 p.m. EDT: National Football League Commissioner Roger Goodell issued a statement mourning the death of Frank Gifford, calling him an "icon."

Frank Gifford was an icon of the game, both as a Hall of Fame player for the Giants and Hall of Fame broadcaster for CBS and ABC. Frank’s talent and charisma on the field and on the air were important elements in the growth and popularity of the modern NFL. He was a great friend to everyone in the league, a special advisor to NFL commissioners, and served NFL fans with enormous distinction for so many decades. We will always remember Frank’s contributions and miss his friendship. Our hearts go out to Kathie Lee and the entire Gifford family.
