Wilt Chamberlain seemed to be a model of fitness. Even after his Hall of Fame basketball career ended, he turned to volleyball and marathons. But for years he had also endured heart problems--and they eventually killed him, Sy Goldberg, Chamberlain's agent and longtime friend, told the Associated Press.

"He had congestive heart failure," Goldberg said the day after Chamberlain died at age 63. "He had deteriorated relatively quickly over the last month or so."

Chamberlain had lost 30 or 40 pounds over the past few weeks as doctors drained his legs of fluid that had accumulated because of his heart trouble, Goldberg said.

The 7-foot-1 Chamberlain, the only player to score 100 points in an NBA game, was found dead in his bed at his Los Angeles area home. "It was just one of those things. He had some [heart] problems in the past, but this just struck quickly," Goldberg said after speaking with Chamberlain's cardiologist, Anthony Reid. Chamberlain's sister, Barbara Lewis, said Tuesday that her brother had undergone dental surgery last week and looked worse than she had ever seen him.

"The cardiac situation was the main thing," Goldberg said.

Reports that Chamberlain had a heart problem arose back in the early 1960s, but he denied them. He was hospitalized for three days in 1992 with a slightly irregular heartbeat. A funeral for Chamberlain, with limited seating for the public, will be Saturday, Goldberg said.

Out of Africa

Rumble in the Jungle II?

That's what an African king has in mind with his wildly improbable bid to hold the heavyweight title rematch between Evander Holyfield and Lennox Lewis in Uganda.

The fight is scheduled for Las Vegas on Nov. 13, with all parties under contract. But Ronald Muwenda Mutebi II--monarch of Buganda, a kingdom of Uganda--offered yesterday to put the bout in Kampala, capital of the East African nation.

The king has lined up more than $15 million for the fight from commercial sponsors in Uganda, London-based spokesman Kizzi Nkwocha said. But U.S. promoters said the Las Vegas location is a done deal. . . .

The Joke is Over

Serena Williams's eyes sparkled and a big smile creased her face when she was asked about playing in a men's tennis tournament because, "Women's tennis is boring."

"I never made that quote," the U.S. Open women's singles champion said when asked about a story out of Germany last week. "I never said anything like that."

According to the story, Williams asked for a wild-card entry into a tournament in Stuttgart, Germany, later this month. Markus Gunthard, director of the tournament, said Williams had asked him for a wild card. Williams said it was a joke that got out of hand. . . .
