Chambers' behaviour 'inexcusable'

Chambers is facing a minimum two-year ban

Sprinter Dwain Chambers has been accused of using the US company at the centre of the THG drug scandal as a "scapegoat" for his own positive test.

Chambers has suggested supplements from US company Balco could be to blame for the steroid THG being in his sample.

But a lawyer representing Balco boss Victor Conte has hit back at Chambers.

Troy Ellerman said: "To use Victor Conte as a scapegoat to try to get out of a two-year ban or potentially a lifetime ban is inexcusable."

Ellerman, speaking to BBC Radio Five Live, said: "I don't know Dwain Chambers but he seems like a smart-enough guy to get where he's at and he's a nationally-known athlete in Brtiain."

Asked if Conte supplied Chambers with THG, he said: "Absolutely not."

Chambers failed an out-of-competition test on 1 August when traces of THG were found in his sample.

A statement by Chambers said his positive test was not "a wilful or calculated attempt on his behalf to deceive the authorities".

The statement added that in eight years of competition, Chambers has "never been tempted to succumb to illegal methods of performance enhancement".

Chambers faces a minimum two-year ban if the B test confirms the discovery in his urine sample of THG.
