Chambers' Positive Thg Test Confirmed

Dwain Chambers' positive test for the designer steroid THG has been confirmed by a second test.

The result of the sprinter's B test matches that of the positive A test, a source close to the testing process revealed this afternoon.

Once UK Athletics has received official notification of the positive B sample, a disciplinary hearing will be set up.

If that hearing finds the European 100 metres champion guilty, he'll face a minimum two-year ban and, under the guidelines of the British Olympic Association's anti-drug stance, he would receive a life ban from the Olympics.

Nick Davies, a spokesman for world athletics' governing body the IAAF confirmed that the 25-year-old's B sample had been tested in Los Angeles on Monday, but said the result had not yet been made public.

"No letter has been sent yet from the IAAF to UK Athletics. That will be tomorrow morning at the latest," Davies said."

UK Athletics will wait until they have received official notification of the result from the B sample before issuing any statement.

Chambers has admitted taking THG, which was discovered on August 1 in an out-of-competition test in Germany, but claims he was unaware of the contents of the supplements he was taking.
