The International Cycling Union (UCI) will open disciplinary proceedings against “a number” of riders after discovering suspicious data in their biological passports, the sport's governing body said on Wednesday. “The riders will be informed early next week,” UCI president Pat McQuaid told a news conference without indicating the exact number of cyclists involved. “Soon after informing the riders, we will inform their teams and national federations. We will name the riders and will start disciplinary proceedings against them,” he added. In Oct. 2007, the UCI and the World Anti-Doping Agency (WADA) announced they would collect blood samples from all professional riders to create a medical profile, or passport, that would be compared to the data registered in doping tests.
