The Italian Olympic Committee (CONI) announced the hearing on its Web site (www.coni.it) on Tuesday. Moreni could face a maximum two-year ban.

Moreni's positive test, in a Tour marred by doping allegations, led to his Cofidis team pulling out of the race last week.

A parade of Italian cyclists have recently appeared before CONI's anti-doping wing.

Giro d'Italia winner Danilo Di Luca, who denies any wrongdoing, is waiting to hear if he faces any sanction for his links to Carlo Santuccione, a doctor accused of supplying doping products to athletes.

Santuccione was due to appear before the anti-doping body on Thursday but CONI said he had informed the committee on Tuesday that he would not be attending. No reason was given.
