Italian golfer Alessandro Pissilli has been suspended after failing a drug test, the Italian Olympic Committee said Wednesday.
Pissilli, who plays on the Italian pro tour, tested positive for the banned diuretic Finasteride at the Omnium National Championship on June 29.
Pissilli has been suspended by the Italian Golf Federation and could face a two-year ban if found guilty of a doping violation.
Golf has come under increased pressure from the World Anti-Doping Agency to introduce random drug testing after South African veteran Gary Player claimed at the British Open last month that some golfers were taking performance-enhancing drugs.
Finasteride is used to treat hair loss but can also mask steroid use, and has been at the center of several recent doping cases.
American skeleton slider Zach Lund missed the 2006 Turin Olympics because of a one-year doping suspension triggered by his use of the drug. He was later cleared of wrongdoing by the Court of Arbitration for Sport.
French runner Nordine Gezzar and former Premier League soccer player Stan Lazaridis of Australia have also tested positive for Finasteride.
