27-year-old Italian cyclist Matteo Priamo has been given a four-year doping ban by the Court of Arbitration for Sport, or CAS. An official source has said that Priamo is banned for supplying the banned blood-booster EPO CERA to his former team mate at CSF, Emmanuelle Sella. Sella, shortly after winning three stages at the Giro d’Italia, tested positive for the drug last year in July. He confessed to using the drug and cooperated with authorities to name Priamo as his supplier, thus earning himself a reduced one-year suspension. Sella has since returned to cycling with Italian team Carmiooro Style-A. The CAS has said that it is “sufficiently established” that Matteo Priamo has violated two articles of the World Anti-Doping Code. Priamo’s suspension has been backdated to begin on February 27th.
