Lance Armstrong Calls New Allegations of Doping "Falsehoods"

Lance Armstrong is fighting back after new accusations from disgraced cyclist Floyd Landis. Landis is accusing Armstrong of using performance enhancing substances.  

A statement from Armstrong and his sponsor, Team RadioShack, called the claims "falsehoods."

It was all part of a dramatic 24 hours for Armstrong, who had a nasty accident during the Tour of California race on May 20.

Blood gushed down his face and Armstrong had to be taken to the hospital for stitches after the collision with another rider. Eight stitches were used to close the cut below his left eye.
