Luis Suarez has received support from World Cup winner Diego Maradona, while his biting victim, Giorgio Chiellini, branded the ban “excessive”.
The Uruguayan is not allowed to train with his club or enter a football stadium yet Spanish side Barcelona remains interested in signing the player from Liverpool.
For their part, Liverpool are seeking legal advice after being denied the services of last season’s leading Premier League scorer until the end of October.
Meanwhile, online gambling firm 888poker says it has terminated its relationship with Suarez with immediate effect.
Suarez, who flew back to the Uruguayan capital Montevideo in the early hours of Friday morning, denied the allegations following his clash with Giorgio Chiellini, claiming the centre-back had bumped into him.
However, FIFA decided he was guilty and gave him the longest ban in World Cup history.
Luis Suarez also received a nine-match international suspension and a fine of 100,000 Swiss francs.
Writing on his personal website, Giorgio Chiellini, 29, said: “I have always considered unequivocal the disciplinary interventions by the competent bodies but, at the same time, I believe that the proposed formula is excessive.
“Now inside me there’s no feelings of joy, revenge or anger against Suarez for an incident that happened on the pitch and that’s done. There only remains the anger and the disappointment about the match.
“At the moment my only thought is for Luis and his family, because they will face a very difficult period.”
Former Argentina captain and coach Diego Maradona declared his support for Luis Suarez on his television show De Zurda on Thursday night.
“The FIFA sanction is shameful, they have no sensitivity towards the fans, they might as well handcuff him and throw him in Guantanamo,” said Diego Maradona, who was wearing a T-shirt bearing the message, “Luis, we are with you”.
“It hurts that they have cut short the career of a lad who is a winner. It’s an excessive suspension, FIFA cannot talk about morals to anyone.
“Suarez didn’t kill anyone. This is an unjust punishment, the act of an incredible mafia.”
Diego Maradona interviewed Uruguay’s president Jose Mujica during the program, broadcast on Telesur TV.
“We Uruguayans are full of anger, those coming from below do not understand anything,” said Jose Mujica.
“We kicked out Italy and England, no doubt they lost a lot of money.”
Jose Mujica claimed FIFA used “a different standard” to judge certain countries.
“That’s what hurts and angers us the most,” he added.
Uruguay will play Colombia in the last 16 on Saturday after qualifying from Group D behind Costa Rica.
