Paris - The French Anti-doping Agency (AFLD) sprang a surprise out-of-competition doping test on seven-time Tour de France winner Lance Armstrong that included a sample of his hair, Armstrong said on his Twitter feed.
"Yet another "surprise" anti-doping control. 24th one. This one from the French authorities. Urine, blood, and hair! Classic," Armstrong wrote on the Twitter.
The AFLD confirmed the test on Wednesday, saying that Armstrong was subject to examinations like any other athlete.
