Armstrong may be open to lie detector test

While Armstrong has refused to respond to the litany of charges against him his lawyer has raised the intriguing prospect of his client sitting a lie detector test to prove his innocence.

Tim Herman said Armstrong would consider the idea if the 26 witnesses who testified against him to the US Anti-Doping Agency (USADA) would do the same.

The USADA stripped Armstrong of his seven Tour de France titles.
