PARIS — Chris Froome failed a doping test during the Spanish Vuelta in September and is facing a suspension from cycling ahead of his attempt to win a record-equaling fifth Tour de France title next year.
Sky said Froome had to take an increased dosage of salbutamol without exceeding the permissible dose after he "experienced acute asthma symptoms" during the final week of the Vuelta.
Froome was expected to attempt to join cycling greats Eddy Merckx, Bernard Hinault and Miguel Indurain on the list of five-time Tour de France champions in July.
Team Sky was established in 2009 by Dave Brailsford, the man behind Britain's 14 medals at the 2008 Beijing Olympics, with the target of producing the country's first Tour champion — a feat accomplished by Wiggins in 2012.
Sky stressed the abnormal result does not mean Froome has breached anti-doping rules and Brailsford insisted he has the "utmost confidence that Chris followed the medical guidance in managing his asthma symptoms, staying within the permissible dose for Salbutamol."
