NFL testing back samples for THG
NEW YORK -- The NFL is rechecking players' drug tests to look for the newly identified steroid THG.
The steroid, at the center of an investigation by the U.S. Anti-Doping Agency, previously was undetectable. But USADA received a used syringe containing the designer steroid from an anonymous coach and then began retesting samples of track and field athletes.
NFL spokesman Greg Aiello said Saturday that "as soon as the report came out about THG, we said we would be testing for it and we are."
That includes previously taken urine samples that were tested by the league for other drugs.
An NFL player testing positive for steroids receives a four-game suspension for the first offense.
Olympic and pro athletes have been subpoenaed by a federal grand jury probing a California laboratory that provides nutritional supplements to athletes.
Victor Conte, whose Bay Area Laboratory Co-Operative was raided in early September by agents of the Internal Revenue Service and a San Mateo County narcotics task force, said in an e-mail to The Associated Press he was told by athletes that 40 of them have been called to testify.
The scope of the grand jury's probe is not known.
