It sounds improbable, but Muhammad Ali says he wants to get back into the ring one more time.

In this week's Newsweek magazine, the three-time heavyweight champion wrote that he is planning on getting in shape to do some sparring, despite his Parkinson's disease that has slowed his speech and movement.

Ali, 57, last fought professionally on Dec. 11, 1981, a 10-round loss to Trevor Berbick. He finished with a 56-5 record and 37 knockouts.

"Now I'm fighting Parkinson's disease. But I don't let it stop me. I still travel, attend to my business, do interviews," Ali wrote in a first-person remembrance for the magazine.

"And let me tell you something that'll shock the Earth. I'm going to train and get in really good shape, lose 35 pounds and do an exhibition in Madison Square Garden with two or three contenders," he wrote. "I'll dance for 15 rounds, and whup 'em. I haven't forgotten. I'll be weighing in at 210 pounds. I'll just say, 'I am returned. Get the contract.' "

Ali travels with his wife, Lonnie, who speaks on his behalf. His speech is limited by Parkinson's, a degenerative nerve disease. His walk is a little slower, but his intellect is unaffected.


On Her Own, V. Williams Triumphs

Playing for the first time at a tournament without a family member accompanying her, Venus Williams routed top-ranked Martina Hingis, 6-3, 6-4, to win the Swisscom Challenge in Zurich.

She did not drop a set in the tournament and earned her ninth career title. She also denied Hingis the chance to win a title in her home country for the first time.

"My parents had confidence in me and I'm glad I didn't disappoint them," said Williams, whose family remained in Florida, caught up in the swirl of studies, work and Hurricane Irene. "I was a little nervous being without them at the start of the tournament. Naturally, as everybody gets older you have to start doing things on your own." . . .

Greg Rusedski rallied to defeat Nicolas Kiefer in the longest final of the CA Trophy in Vienna, winning 6-7 (7-5), 2-6, 6-3, 7-5, 6-4. The match lasted 3 1/2 hours. . . .

Marcelo Rios defended his Heineken Open title with a 6-2, 7-6 (7-5) victory over Sweden's Mikael Tillstrom in Singapore. Rios did not drop a set in the tournament.
