De Rossi was axed after the Giallorossi man was seen throwing a punch at Mauro Icardi during their draw with Inter Milan.
“The code of ethics is our regulation,” Prandelli told a Press conference. “From the first day of the season, if I have seen something that I deem inappropriate, I will not call up that player.
“With De Rossi, I saw it on television and decided. The lad has accepted the decision.
“I don’t want any crazy things happening in Brazil, so this is a warning.”
