Germany's Andreas Kloeden has been accused of doping in 2006 Tour de France.
Experts investigating the procedures of two Freiburg University Clinic doctors who worked for cycling team T-Mobile allege German rider Andreas Kloeden doped during the 2006 Tour de France.
Kloeden, who finished second in the Tour three years ago and is currently under contract with the Astana team, is quoted in the 63-page report published by a three-man commission after a two-year investigation.
"As well as Patrik Sinkewitz, at least two other riders received blood transfusions with the doctors help: the riders are Matthias Kessler and Andreas Kloeden," the report says.
Sinkewitz was given a two-year suspension from cycling for doping in 2007 and suspended for two years, while Kessler was also hit with a two-year ban in early 2008 for doping, but Kloeden has never failed a doping test.
The report says doping was systematic in T-Mobile, formerly known as Deutsche Telekom, between 1995 and 2006 and the drugs were administered by doctors Lothar Heinrich and Andreas Schmid.
The doctors were sacked by Freiburg University in 2007 after admitting having helped administer doping products and an investigation was launched into their conduct.
