Re-testing of blood samples for 10 riders (not 14 as originally reported) who competed in the 2008 Tour de France began on Monday.  Under the direction of the French Anti-Doping Agency (AFLD), anti-doping laboratories in Paris and Lausanne are testing for CERA, a form of EPO.  Testing is expected to last about two weeks but the results for three of the riders should be known this Friday or next Monday.  (source:  L'Equipe)
