Jacques Rogge, International Olympic Committee (IOC) president, has announced that Marion Jones, who last month admitted to doping, has been stripped of her five Sydney Games medals.
The IOC's move follows the two year ban imposed on the 31-year-old in November by the International Association of Athletics Federations (IAAF), the sport's governing body.
"We've disqualified Miss Jones from the 2000 Olympic Games and declared her ineligible from Beijing [the 2008 Olympics]," Rogge confirmed.
"She is disqualified and scrapped from the results.
"She is disqualified and scrapped from the results."
"We disqualified Marion Jones from the five events she took part in Sydney and for one event in Athens [the 2004 Olympics] which is the long jump where she was fifth."
Jones was the track and field star of the 2000 Olympic Games in Sydney, winning gold in the 100m, 200m, and 4x400m relay, while also picking up two bronzes in the long jump and 4x100m relay.
She became the first woman to win five medals in a single Olympics.
However her achievements have been scratched from the record books after her admission that she was using the prohibited substance known as 'the clear' beginning on September 1, 2000.
Redistribution of medals delayed
Jones had pre-empted Wednesday's IOC decision by handing back her five Olympic medals last month after she told a US court of her use of performance-enhancing drugs.
The American also pleaded guilty to two counts of providing false statements to federal investigators and check fraud and will be sentenced in January.
Rogge said the IOC would redistribute the disgraced sprinter's medals at a later date.
The reason for the delay is that the logical recipient of Jones' 100m gold, runner-up Ekaterini Thanou from Greece, was herself given a two-year ban for allegedly faking a motorbike crash to cover up missing a drug test during the 2004 Athens Games.
"We want to be sure of the athletes who receive Jones' medals," Rogge said without mentioning Thanou specifically.
"We're going to wait until the end of the BALCO [steroid case] inquiry.
"Other names might emerge."
