On federal court in Friday, former pro Tammy Thomas pleased not guilty to charges of lying to a grand jury in the BALCO steroid case according to All Headline News. The 2001 world silver track sprint medalist, who was banned for life from the sport after a positive drug test for Norbolethone in August 2002, was indicted on three counts of perjury and one of obstruction of justice. She was released on bond after entering her plea. If convicted, Thomas could spend up to five years in prison for each count plus pay a US$250,000 fine. The court has not set a trial date.
