Fiorentina striker Adrian Mutu has again tested positive for a banned substance, the Italian Olympic Committee has announced.
The Romanian marksman was sacked by Chelsea in 2004 for taking cocaine that also earned him a seven-month ban.
Mutu has since rebuilt his career with the likes of Juventus and now Fiorentina, prior to his positive test following their win over Bari.
A statement from CONI, which acts as Italy's anti-doping body, revealed traces of the substance sibutramine were found in a sample provided by him following the Serie A match against Bari on 10th January.
The statement read: "CONI announces that a positive test has been confirmed on Adrian Mutu with the presence of metabolics of sibutramine found in tests done by the FIGC on January 10 after the Serie A game between Fiorentina and Bari."
Mutu scored in a 2-1 Fiorentina victory and it remains to be seen what action, if any, the Italian football federation will take against the striker.
The ex-Juve man is reportedly facing a one to four-year ban if the results of his first sample are indeed in breach of Italy's anti-doping regulations.
Fiorentina, who qualified from the Champions League group stages but have slipped to ninth in Serie A after a poor run of form, were not immediately available to comment.
