The story first broke out of ESPN. NBC Sports Chairman Dick Ebersol has announced that NBC Sunday Night Football color commentator John Madden has decided to call it quits.

Madden, who coached the Oakland Raiders to a Super Bowl victory, has had his fingerprints all over the NFL landscape for over forty years As a player, head coach, and successful commentator who most notably teamed up with Pat Summerall and Al Michaels.

He's also staked his claim to pop culture where he was a popular pitchman for products. He was the subject to comedian Frank Calliendo's popular sketches, and his name will forever be linked to the biggest video game franchise of all time in the Madden series. Madden will be replaced in the booth by Cris Collinsworth.

This also brings back a rumor that died a little while back: Is Al Davis trying to bring John Madden back to the Raiders?

His retirement also confirms that Brett Favre will not unretire.
