Credit Agricole rider Dmitriy Fofonov has been handed a three-month ban after testing positive for a banned stimulant at the Tour de France.
Traces of heptaminol - which is found in products aimed at improving blood circulation - were found in a sample provided by the 31-year-old Kazakh.
He was informed of the positive test at the end of the race's 21st and final stage to the Champs Elysees, where he finished 19th overall.
French national anti-doping agency (AFLD) chief Pierre Bordry on Wednesday said there was "considerable evidence" of doping irregularities from blood transfusions taken at this year's Tour de France.
"We possess considerable evidence from blood transfusions. We will only say later who it is," Bordry told German TV station ZDF.
Bodry added that anti-doping officials were concentrating on looking for traces of banned blood booster EPO, "but we will soon be able to test the transfusions thanks to a new procedure, and we are going to do these tests.
