Sean Sherk, the reigning UFC World Lightweight Champion, who last competed on July 7, 2007 in Sacramento, has tested positive for Nandrolone Metabolite. He has been fined $2,500. His suspension period runs from the conclusion of his bout on July 7, 2007 through the remainder of his licensing year which is June 26, 2008. Furthermore, he has been assessed an additional 10 days in order to fulfill the terms of his suspension (365 total days). The additional days will be added at the beginning of his next licensing year when he reapplies.
Normal levels of Nandrolone range from 2 ng/mL (average person) to 6 ng/mL (athlete engaged in rigorous activity). Mr. Sherk's reported level certified by the Director of Science and Technology from the laboratory that conducted the tests was 12 ng/mL. Both the "A" sample and "B" sample were tested and confirmed as positive.
