(CNN) -- Fiorentina striker Adrian Mutu has tested positive for a banned substance, the Italian Olympic Committee (CONI) have announced on Thursday.
A statement from CONI revealed traces of the anti-obesity drug sibutramine were found in a sample provided by the Romanian international following the Serie A match between Fiorentina and Bari on January 10.
Mutu scored in the game, which Fiorentina won 2-1.
A statement from CONI read: "CONI announces that a positive test has been confirmed on Adrian Mutu with the presence of metabolics of sibutramine found in tests undergone on January 10 after the Serie A game between Fiorentina and Bari."
This is Mutu's second failed drug test. In 2004, the 31-year-old was sacked by Chelsea after testing positive for cocaine -- and was given a seven-month worldwide football ban.
After serving his ban, Mutu joined Juventus in January 2005 before moving to Fiorentina at the end of the following season.
Chelsea sued Mutu for breach of contract, and the player is still in the process of making a third appeal against a fine levied at more than 17 million euros.
Mutu is under contract with the Viola until June 2012 and has scored four goals in 11 league appearances this season.
