Mayo cleared after B sample comes back negative

Iban Mayo was informed by the Spanish Cycling Federation on Monday that the testing of his B sample from the Tour de France positive test on July 24 has come back negative. The Saunier Duval - Prodir rider was originally declared positive for the blood booster EPO from a sample taken on the Tour's second rest day, but has now been cleared for a return to racing.

According to AFP, the federation confirmed that there had been a mistake in the testing of Mayo's A sample, which was carried out at the Châtenay-Malabry anti-doping laboratory in Paris. The B sample was tested by a separate laboratory in the Belgian city of Gent, and was confirmed by another test done in Australia.
