John Madden’s last game as a football announcer was the 2009 Super Bowl which was decided in the final moments of the game. Madden 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 said his health is fine, but at the age of 73, he wants to spend more time with his family. His 50th wedding anniversary is this year, and his five grandchildren are old enough to notice when he’s gone.

“The thing that made it hard is not because I’m second guessing: ‘Is it the right decision?’ But I enjoyed it so damn much,” Madden said. “I enjoyed the game and the players and the coaches and the film and the travel and everything.”

Boston Celtics head coach Doc Rivers has announced that star forward Kevin Garnett might not be available to play for the entire playoffs.

The Boston Globe is reporting that Rivers stated in an interview this morning that “there’s no way he can play,” but did leave open the chance that he might return at some point in the postseason.

Unfortunately, that return is unlikely as Garnett was having trouble running in Wednesday morning’s practice due to his injured right knee. Rivers said that Garnett will continue to get treatment and if it goes well he might be able to return to play at a later date in the playoffs.

The All-Star had already missed a full month of action due to a posterior muscle strain of his right knee, but he returned on March 20 and played the next four games. However, after playing at Orlando on March 25, he has sat out Boston’s final nine games of the season.

Ocar De La Hoya made his announcement at an outdoor plaza across the street from Staples Center, where a bronze statue of the 36-year-old Golden Boy stands.

“I’ve come to the conclusion that it’s over,” the East Los Angeles native said before hundreds of fans, including comedian George Lopez and Oscar-nominated actor and former fighter Mickey Rourke. “It’s over inside the ring for me.”

De La Hoya retired four months after he was beaten by Manny Pacquiao, his fourth loss in his last seven fights. He has not defeated a formidable opponent since Fernando Vargas in 2002. Age and diminished skills led to losses in recent years to Felix Trinidad, Shane Mosley, Bernard Hopkins and Floyd Mayweather Jr.

He won his last title in May 2006, beating Ricardo Mayorga in six rounds for the WBC 154-pound belt. He finished with a record of 39-6 and 30 knockouts.

The right-hander was the American League Rookie of the Year in 1976, when he went 19-9 with a 2.34 ERA and 24 complete games. But injuries cut short his career, and he ended up spending only five seasons in the major leagues, all with the Detroit Tigers. He was 29-19 with a 3.10 ERA.

“The entire Detroit Tigers organization was saddened to learn of the passing of former player Mark Fidrych today,” the Tigers said in a statement. “Mark was beloved by Tigers fans and he was a special person with a unique personality. The Tigers send our heartfelt condolences to his family and friends.”

Worcester County district attorney Joseph D. Early Jr. said a family friend found Fidrych about 2:30 p.m. Monday beneath a dump truck in Northborough, Mass., about 35 miles west of Boston. He appeared to have been working on the truck, Early said.
