LAUSANNE: Spanish cyclist Alejandro Valverde has lost his final appeal to Switzerland's supreme court to overturn a doping suspension. The Swiss Federal Tribunal said Monday it dismissed Valverde's challenge to a Court of Arbitration for Sport decision which banned the 2009 Spanish Vuelta winner until January 2012. The CAS ruled last May in favor of the International Cycling Union and World Anti-Doping Agency. The two organizations wanted the 30-year-old Spaniard banned worldwide after he'd been excluded from racing in Italy.
