DUBAI, United Arab Emirates -- The IOC has disqualified a Polish cross-country skier who tested positive for a blood-boosting drug at the Vancouver Olympics.

The International Olympic Committee stripped Kornelia Marek of all her results from Vancouver. She did not win any medals.

Marek tested positive for EPO after helping Poland finish sixth in the 20K relay. She admitted taking injections but said she believed the substances were allowed.

Marek has already been suspended for two years by Poland's ski federation.

The IOC told the international ski federation Thursday to modify the Vancouver results and consider any further action.
