NEW YORK John Madden is retiring from football announcing, where his enthusiastic, down-to-earth style made him one of sports' most popular broadcasters for three decades.

The Hall of Fame coach spent the last three seasons on NBC's "Sunday Night Football." His final telecast was the Super Bowl in February.

"You know at some point you have to do this I got to that point," Madden said on his Bay Area radio show today.

Cris Collinsworth will replace Madden, moving over from the network's studio show, NBC Sports chief Dick Ebersol said. Collinsworth filled in when Madden took a game off last October.

Madden said his health is fine, but at the age of 73, he wanted to spend more time with his family.

His "Madden NFL Football" is the top-selling sports video game of all time.

Madden began his pro football career as a linebacker coach at Oakland in 1967 and was named head coach two years later, at 33 the youngest coach in what was then the American Football League.

Madden led the Raiders to their first Super Bowl victory and retired in 1979. He joined CBS later that year.

He worked at CBS until 1994 when the network lost rights to broadcast NFL games, leading him to switch to Fox. He left Fox in 2002 to become the lead analyst for ABC's "Monday Night Football" and joined NBC in 2006 when that network inaugurated a prime-time Sunday game.

Madden was inducted into the Pro Football Hall of Fame in 2006.
