Fiorentina striker Adrian Mutu has failed another doping test, the Italian Olympic Committee announced.

The Romania international tested positive for traces of sibutramine, an anti-obesity drug, after the Coppa Italia quarter-final against Lazio on January 20.

That was Mutu's second failed test this month. CONI revealed yesterday that the 31-year-old had tested positive for the same substance on January 10 after a Serie A game between Fiorentina and Bari.
