A failed appeal against a two-year sentence means that former cycling medical adviser Bernard Sainz will have to spend a year in jail.
The former soigneur was implicated in the 1998 Tour de France Festina scandal, and in 2002, Sainz was stopped at a traffic control and a haul of illegal substances was found.
A subsequent search of cyclist Frank Vandenbroucke’s house revealed EPO, morphine and clenbuterole, which helps building muscle mass. Vandenbroucke died in October last year of a pulmonary embolism.
On Thursday, a Paris court rejected Sainz’s appeal against his sentence after being convicted of “incitement to doping” and illegally practising medicine in 1998 and 1999.
