NEW YORK (SI.com) -- Legendary NFL broadcaster John Madden has made his last call.
NBC announced the former coach's plans to retire Thursday morning. Though he spent the last three years working NBC's Sunday night NFL game, he served as an analyst on all four major television networks since retiring as the Oakland Raiders coach in 1979.
"It's time," Madden said. "I'm 73 years old. My 50th wedding anniversary is this fall. I have two great sons and their families and their five grandchildren are at an age now when they know when I'm home and, more importantly, when I'm not."
