Her reputation is gone and now so are Marion Jones’ Olympic medals.

Jones gave back the five medals she won at the Sydney Olympics yesterday and agreed to forfeit all other results dating back to Sept. 1, 2000, further punishment for her admission that she was a drug cheat.

The three gold medals and two bronzes were turned over to U.S. Olympic Committee and U.S. Anti-Doping Agency officials at her attorneys’ office in Austin, Texas. They are en route to USOC headquarters in Colorado Springs, and the USOC will return them to the International Olympic Committee.

“We’ve done what we can,” the USOC’s chief executive officer, Jim Scherr, said. “We caught the person who was not clean. We’ve got the medals in our possession, and we will return them to IOC.” Jones won golds in the 100 and 200 meters, as well as the 1,600 relay. She won bronzes in the 400 relay and the long jump. It will be up to the IOC to decide what to do with the medals and whether to vacate Jones’ results from Sydney — which could cost her relay teammates their medals, too.

Scherr and USOC chairman Peter Ueberroth both said they would support the IOC nullifying the relay results, and encouraged the other Americans to give back their medals.

Jearl Miles-Clark, Monique Hennagan, Tasha Colander-Richardson and Andrea Anderson all won golds as part of the 1,600-meter relay. Chryste Gaines, Torri Edwards, Nanceen Perry and Passion Richardson were on the 400-meter relay team.

Both Edwards and Gaines have served doping bans since the 2000 Olympics.

“It’s our opinion when any sporting event is won unfairly, it’s completely tarnished and should be returned. The relay events were won unfairly,” Ueberroth said. “It’s very unfortunate, but your result involved cheating, so the result is unfair to the other athletes of the world.”

Jones pleaded guilty Friday to lying to federal investigators about using steroids, saying she’d taken the designer steroid “the clear” from September 2000 to July 2001. “The clear” has been linked to BALCO, the lab at the center of the steroids scandal in professional sports.

After Friday’s court hearing, Jones announced her retirement, but yesterday, she accepted a two-year ban and agreed to forfeit any results dating back to Sept. 1, 2000.

Her 100-meter win and long jump bronze medal at the 1999 world championships will stand. No one answered the door yesterday at Jones’ house in Austin, Texas.

If the IOC does vacate Jones’ results, the standings likely will be readjusted, with the second-place finisher moving up to gold, third to silver, and fourth to bronze.

“Obviously we’re concerned about a level playing field all the time. But we have no jurisdiction or nothing to say about that,” Ueberroth said. “We have a responsibility to compete fairly. That’s our system, and that’s the way we’re going to live.”

Ueberroth also said the USOC board had written letters of apology to 205 national Olympic committees, as well as to the people of Australia. As part of those apologies, Ueberroth said the USOC is pledging that it will bring a clean team to next summer’s Olympics.
