As many as four members of the U.S. national bobsled team face suspension because of possible drug use, including the use of steroids, according to a published report.

Eight unnamed sledders have already failed one drug test, and the United States Bobsled and Skeleton Federation is waiting for results of a second sample before taking disciplinary action, according to Saturday's Watertown Daily Times.Should the samples come back positive, it would be the worst drug scandal in federation history. Federation Judiciary Committee Chairman John D. Cogar said told the Daily Times there is a 90-percent chance the second sample tests will be positive.

"If the tests come back positive, these athletes are done," Cogar warned. "They're done. They're done for this year."

Four others sledders are expected to test positive for having in their system cold medicine that has been banned, a more minor offense, the report said.

Under U.S. Olympic Committee guidelines, any athlete testing positive for a banned substance is expelled from competition for at least six months.

A second offense results in a suspension of at least four years, said federation Executive Director David E. Heim.

Heim said 35 members of the federation were tested last month while at the world team trials in Calgary, Alberta. Of the first samples which tested positive, three were for anabolic steroids, three or four for pseudoephedrine, a cold remedy, and one for morphine, the newspaper reported.
