The IOC has decided to postpone the reallocation of the five Olympic medals returned by Marion Jones following her admission that she began doping before the 2000 Sydney Games.
The International Olympic Committee had been expected to rule on the medal changes during its three-day executive board that started Monday.
But board member Denis Oswald said the IOC wants more information from the BALCO steroid investigation before deciding whether to upgrade doping-tainted Greek sprinter Katerina Thanou to Jones' gold in the women's 100 meters.
Oswald said the IOC also would afford hearings to Jones' American relay teammates before deciding whether to strip them of their Sydney medals.
"We don't want to do it piece by piece," he said. "We want to wait until we have full information."
The IOC executive board is still expected to formally strip Jones of her medals on Wednesday. However, final decisions on how to readjust those medals will probably take months, Oswald said. Oswald, a Swiss lawyer, sits on the three-member IOC disciplinary commission investigating the Jones and BALCO case. Jones won gold medals in the 100, 200 and 1,600-meter relay in Sydney, and bronze medals in the long jump and 400-meter relay. After years of denying drug use, she acknowledged in court in October that she started doping before the Sydney Olympics. She has returned her medals.
Last month, the International Association of Athletics Federations erased all of Jones' results dating to September 2000 and recommended that her relay teammates also be disqualified and lose their medals.
