Spanish rider Moises Duenas, kicked out of the Tour de France, has blamed a Spanish doctor for his positive test for the blood booster erythropoietin (EPO), the daily El Pais reported on Saturday.

Duenas, who was charged with “use and possession of poisonous substances” before a court at Tarbes, southwestern France on Thursday, had claimed that the products were sold to him by Spanish doctor Jesus Losa.

But the former Euskaltel-Euskadi team doctor denied “ever providing Duenas with prohibited products” and was ready to testify as such before the French justicial system.

El Pais said that Losa’s name came up several years ago in connection with Scottish rider David Millar and the Cofidis doping affair, but he was never questioned.

Barloworld rider Duenas is one of three cyclists to fail a drugs test during this year’s Tour de France along with compatriot Manuel Beltran of Liquigas and Italy’s Riccardo Ricco of Saunier-Duval.
