Markus Zberg, a former BMC and Gerolsteiner rider who retired in August this year, has been accused of buying EPO from Bernhard Kohl's manager, Stefan Matschiner. Kohl tested positive for third generation EPO-CERA last year and has since cooperated with Austrian anti-doping authorities, disclosing many details about his own doping practices.
