Former Brazil international Mancini has been sentenced to two years and eight months in prison after he was found guilty of rape.
Former Inter Milan and AC Milan winger Mancini, who is currently under contract with boyhood club Atletico Mineiro in Brazil, was accused on a sexual attack on a woman in December 2010.
The 31-year-old made six appearances for Brazil during his five-year spell with Roma. He signed for Inter Milan in 2008, but joined AC Milan on loan in the 2009-2010 season and then returned to his homeland in January this year.
Mancini had made 25 appearances for Atletico Mineiro in the current Brasileiro campaign.
