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."
