Lazio striker Mauro Zarate must serve a three-match suspension following his conduct in the 3-1 defeat to Bologna.
The Argentine forward became involved in a confrontation at the end of the match and threw the ball at an opponent.
He has now been hit with a ban and will miss the upcoming matches against Fiorentina, AC Milan and Chievo.
The news will come as a blow to Lazio as Zarate has been a key figure in their push for honours this season.
His form has been so impressive that he has been linked with a move away from the club, although reports of a switch to Juventus have been played down.
Bologna forward Henry Gimenez, meanwhile, has been suspended for two games for his part in the same incident.
