Italian Gianni Da Ros will not have to serve a 20-year suspension for trafficking in banned substances, the Court of Arbitration for Sport decided.
The court partially upheld the appeal by Da Ros, who asked to have the ban reduced to two years.
Da Ros was arrested in March, 2009 as part of a large operation by the Italian police to stop the distribution of doping products in fitness clubs.
In November, 2009, the Anti-Doping Tribunal of the National Olympic Committee of Italy (CONI) found him guilty of several WADA code violations, including the use, possession, trafficking and administration of banned substances and imposed a 20-year ban.
The CAS said it "confirmed the existence of the infractions committed by the Athlete", which reportedly included the use and distribution of Human Growth Hormone.
However, the court "considered that a twenty-year ban was not justified and has reduced it to a period of four years which corresponds to the standard suspension provided by Article 10.3.2 of the World Anti-Doping Code."
Da Ros will be eligible to race again March 11, 2013, four years after he was first excluded from competition by his Liquigas team. He will be 26 years old when he returns.
