Contador can’t escape doping allegations

German authorities said Tuesday they have received documents from doping expert Werner Franke that he claims show Tour de France winner Alberto Contador was involved in doping.

Franke said he has documents from last year’s Operation Puerto doping investigation in Spain which show that Contador, a Spaniard who won the doping-marred Tour on Sunday, had taken HMG-Lepori as a testosterone booster and an asthma product called TGN.

Contador, who rides for the Discovery Channel team, missed the 2006 Tour when his former team, Liberty, was disqualified because he and four other riders – plus the team director and doctor – were allegedly linked to Operation Puerto.
