"A disciplinary procedure has been requested against the Spanish rider Carlos Barredo for apparent violation of the Anti-Doping Rules on the basis of the information provided by the blood profile in his biological passport," the UCI said in a statement.
Barredo was suspended by his team Rabobank pending the result of a Spanish federation verdict, the Dutch outfit said.
"While awaiting the verdict of the Spanish federation and the final result, Carlos Barredo will be suspended. His contract will expire at the end of 2012," Rabobank said in a statement.
Barredo, 31, has a 2010 Tour of Spain stage to his name and won the 2009 Clasica San Sebastian.
