The Italian Football Federation said it had considered the "particular delicacy" of the case.
The Ghanaian global walked off the pitch in Pescara's game against Cagliari last Sunday after fans of the home side rained racist insults on him.
Mr. Pius Enam Hadzide, Deputy Sports Minister, has condemned Caglieri Football Club's fans for racially abusing Sulley Muntari during a league match.
On Monday, the United Nations High Commissioner for Civil rights, Zeid Ra'ad al-Hussein, applauded Muntari for his reaction during Cagliari's 1-0 win. How could I be punished when I was the victim of racism? FIFPro said it was surprised that Pescara themselves did not appeal, instead leaving it to the player with the help of the Italian Players' Union. "All of us felt the decision was wrong because there is a clear protocol in place and the player had followed that protocol".
The last few days have been very hard for me.
FIFPro had called for the bookings to be "rescinded", arguing that "Muntari was well within his rights to approach referee Daniele Minelli, as the first point of reference, to make his grievances known and seek a solution".
"So, albeit belatedly, the authorities in Italy have now made the correct decision".
"The referee's not just there to stand on the pitch and blow his whistle". Muntari said on Sky Calcio after the game "That sets a bad culture".
Juventus legend Alessandro Del Piero supported Muntari, he said: "You handled things perfectly".
"(The referee) told me I should not talk to the crowd.
"Muntari left us down to 10 men, he left of his own volition when we could've still had our say in the final minutes". I asked him if had heard the insults. Pescara, bottom of the table, have already been relegated.
