February 7 - Lance Armstrong has been given a two-week extension by the United States Anti-Doping Agency (USADA) after offering to "assist in the effort to clean up the sport of cycling".
Armstrong had originally been given until yesterday to confess all under oath after admitting to doping during each of his seven Tour de France triumphs in a televised interview with Oprah Winfrey last month.
USADA has now set a new deadline.
"We have been in communication with Mr Armstrong and his representatives and we understand that he does want to be part of the solution and assist in the effort to clean up the sport of cycling," said USADA chief executive Travis Tygart.
"We have agreed to his request for an additional two weeks to work on details to hopefully allow for this to happen."
USADA claimed last year that Armstrong had led "the most sophisticated, professionalised and successful doping programme sport has ever seen".
Armstrong may still face a criminal investigation by Federal authorities for obstruction, witness tampering and intimidation.
A previous criminal inquiry for crimes reportedly including drug distribution, fraud and conspiracy was suddenly dropped a year ago.
