RadioShack insists bungling Spanish Anti-Doping Agency officials are responsible for Chris Horner missing an out of competition anti-doping test on Monday morning.
Horner became the oldest winner of a Grand Tour on Sunday when he secured victory in the Vuelta a Espana at the age of 41 in the biggest triumph of his career.
Reports emerged this morning that Horner failed to complete a random test, but RadioShack has issued a statement accompanied by screenshots of emails sent by the American to clarify that the Spanish Anti-Doping Agency is at fault.
"Chris Horner updated his whereabouts with United States Anti-Doping Agency before the start of the final stage," the statement read.
"He gave USADA the name of his hotel for the night, phone number and room number for his one-hour window between 6 to 7am.
"This is all according to the rules and Chris Horner received a confirmation email.
"The anti-doping inspectors from the Spanish Anti-Doping Agency that were asked to do the test by USADA showed up at the wrong hotel in Madrid, where the team was staying but Horner was obviously not to be found."
RadioShack is frustrated that news of the missed test was made public.
"The team believes the communication between the Spanish Anti-Doping Agency and the media is a violation of the privacy of Chris Horner, especially since it comes down to a clear mistake by the tester," the statement read.
"The team will seek compensation for this matter with the responsible anti-doping agencies."
