Austrian-based German Jorg Jaksche has been convicted of doping and handed a one-year suspension by anti-doping authorities in Vienna on Wednesday.

Anti-doping committee member Gernot Schaar said Jaksche's ban would run until July 2, 2008, after Jaksche was convicted of using growth hormones and having been involved in blood doping. It is thought that Jaksche received a lighter-than-normal sentence because he has been cooperating with authorities.

The German, one of many riders implicated in the Operacion Puerto doping affair in Spain, made a series of stunning revelations in recent months, including admitting that he has doped since 1997.

Jaksche, the 2004 Paris-Nice winner who joined the Russian second division outfit Tinkoff in April, also implicated his former teams Polti, ONCE, CSC and Telekom in organised doping.

Operacion Puerto erupted in May 2006, when Spanish police raided the offices of Spanish sports doctor Eufemiano Fuentes and found bags of blood, banned substances and the names of 200 athletes, including 60 cyclists.

Jaksche was linked to one of the codenames found on the bags of blood, but he had previously denied that the moniker "Bella Jorg" related to him.

In an interview published in German weekly Der Spiegel in July, Jaksche admitted his involvement in the blood-doping network.

"I'm Bella. It's my blood which was found in three bags (at Dr Fuentes offices). I was a client of Dr Fuentes from 2005 to 2006 in Madrid," admitted the 30-year-old former T-Mobile rider.

Germany's 1997 Tour de France winner Jan Ullrich was also implicated, as was Italian Ivan Basso, who has since been handed a two-year ban.
