The Liverpool striker risks a lengthy ban, reportedly as much as six months at international and club level, after he was caught biting Chiellini’s shoulder.
“These things happen in the box,” Suarez was quoted as telling Uruguayan media.
“We were in contact, chest against shoulder, and I got a knock to the eye.”
Yet when Suarez fell, he was clearly holding on to his teeth in pain, while Chiellini showed a visible bite mark.
This is, incredibly, the third time in his career that Suarez has been caught on camera biting an opponent.
“Suarez is a sneak and he gets away with it because FIFA want their stars to play in the World Cup,” said Chiellini on Sky Sport Italia.
“I’d love to see if they have the courage to use video evidence against him.
“The referee saw the bite mark too, but he did nothing about it.”
Despite his disgusting behaviour, ecstatic Uruguayans are defending their beloved striker tooth and nail - but mostly tooth - claiming that the Liverpool forward's lethal finishing is far more important than his straying teeth.
"We needed to win, so if you have to hit you hit, if you have to bite you bite," said Barbara Giordano, a 26-year-old law student in Montevideo.
"It's the 'Garra Charrua'!," she exclaimed in reference to Uruguay's legendary fighting spirit.
Others are taking the route of simply denying what was clear for the world to see, both in the original footage and via the marks on Chiellini's shoulder.
"There was no bite, that's what the press says to kill Suarez," said Pablo Dilan, a 38-year-old print shop worker.
The country's national newspaper, El Pais, even tried to make a joke of it, running a headline saying, "Suarez's mouth slips again!"
Some Uruguayans, however, are furious.
"This kid can't control his biting and attacking issues," said Luis Lara, a 52-year-old shopkeeper. "That makes all of us Uruguayans look bad."
Others are gritting their teeth out of fear Suarez may be banned from the rest of the tournament. He has already twice been suspended from club soccer for biting.
"We couldn't believe he was doing it again," said Juan Santestevan, a 33-year-old web worker.
"It's a problem for all of us if they ban him... I don't think he deserves a ban because the other guy also elbowed him. Suarez gets out of control when things don't work out for him, but that's no worse than the kicks they gave him."
