Bernhard Kohl, the 2008 Tour de France King of the Mountains winner has provided testimony to help jail his former manager, Stefan Matschiner, for doping offences.

Matschiner was convicted at a criminal court in Vienna yesterday of providing Kohl and other pro cyclists and athletes with EPO, testosterone, insulin and growth hormones between 2005 and 2008.

Matschiner, 35, had claimed he had stopped supplying the athletes before mid-2008 when the activity was criminalised in Austria, carrying a jail sentence of up to five years. Kohl testified that his former manager continued to supply him with drugs until September 2008, after it had become a criminal offence to do so.

The court gave Matschiner a 15-month prison sentence, 14 months of which were suspended.

Bernhard Kohl finished third in the 2008 Tour but later admitted to his doping activities before retiring from the sport.
