Lazio captain Stefano Mauri has had his match-fixing ban reduced from nine to six months by Italy's sports arbitration court, allowing him to play again from next month.
Mauri was banned for six months in early August for failing to report match-fixing in the Lecce-Lazio Serie A match in May 2011.
Italy's football federation added three months to the ban in October after an appeal.
The reduction means the ban will expire on February 2 and Mauri can play the February 9 derby with Roma.
The arbitration court is the third and final level of appeal in Italian sports justice, which will be reformed this year.
More than 50 people have been arrested in Italy for match-fixing since mid-2011, with matches under investigation by prosecutors in Cremona, Bari and Naples.
