Fiorentina striker Adrian Mutu has tested positive for a banned substance, according to the Italian Olympic Committee.
A statement said traces of anti-obesity drug sibutramine were found in a sample given after a Serie A match between Fiorentina and Bari on 10 January.
The Romania international tested positive for cocaine in September 2004 when playing for Chelsea.
Mutu was subsequently banned for seven months by the Football Association.
However, the 31-year-old could face the prospect of a ban of up to four years for a second drugs-related offence.
Mutu has been in excellent form for the Florence-based club, scoring five times this season - including a goal in the 2-1 win over Bari.
But his problems have further exacerbated with a Swiss Federal Court nearing a ruling on Mutu's appeal against the Court of Arbitration for Sport, which said he must pay Chelsea 17m Euros (£14.62m) for breach of contract.
Sibutramine is an appetite suppressant drug used for obese people, although it was recently banned in the UK amid fears over the increased risks of heart attacks and strokes.
