The midfielder faces a spell on the sidelines as he's been punished by the Lega Serie A for his red card in this weekend's 3-2 loss against the Giallorossi's city-rivals, Lazio
De Rossi was dismissed by referee Gianluca Rocchi in the closing seconds of the first half after he slapped Stefano Mauri, and the Lega Serie A does not take the midfielder's action lightly.
The 29-year-old was already dropped from the Italy squad by national team coach Cesare Prandelli following his red card, and he will now have to watch Roma's next three league games from the stands, too.
His suspension means that De Rossi misses the Serie A matches versus Torino, Pescara and Siena.
Roma will also be without the likes of Nicolas Burdisso and Panagiotis Tachtsidis versus Torino as the duo was handed a one-match ban after they both received their fourth yellow card of the season against Lazio.
