French rider Sylvain Georges has tested positive for a \"specified substance\" during the ongoing Giro d\'Italia, according to cycling\'s world governing body, the UCI. The UCI said Georges had produced an \"adverse analytical finding\", with the stimulant heptaminol showing up in a urine sample collected during the Giro\'s seventh stage on May 10. \"Mr Georges has the right to request and attend the analysis of his B sample,\" the UCI said. \"The UCI Anti-Doping Rules do not impose a provisional suspension given the nature of the substance, which is a specified substance.\" But the AG2R rider did not start Wednesday\'s 11th stage. It now falls to the French cycling federation to decide whether or not to open disciplinary proceedings against Georges. From: AFP
