One of the sports world's most popular couples are splitting up. NFL play-by-player Pat Summerall announced Tuesday that he is leaving Fox Sports and his broadcasting partner of 21 years, John Madden after he and Madden call the Super Bowl on Feb 3. But the 71-year-old former New York Giant insists he's not retiring. "I still want to do games," he said. "I still want to work with the NFL."
