Bans for Roma pair
Both were sent off during Sunday's dramatic late 3-2 victory at Bari for violent conduct and have been handed a three-game suspension, the same number of matches remaining in this campaign.
De Rossi was red-carded for an elbow to Simone Bentivoglio's face while Perrotta was deemed to have punched an opponent in the back, although TV images suggested it was not very forceful.
Roma trail city rivals Lazio by one point in the race for fourth place and the final Champions League qualifying spot. They are also level on points with Udinese while Juventus are only three points behind them following their win at Lazio on Monday night.
Lecce forward David Di Michele has also received a three-game ban after video evidence was used to show he struck Bostjan Cesar in their match with Chievo on Sunday.
