World Cup organizers scrambled Wednesday to quickly decide on a punishment before Uruguay plays Colombia Saturday in the round of 16.
"We have to resolve it either today or tomorrow," FIFA disciplinary panel member Martin Hong told reporters Wednesday. "It's our duty to see justice done."
The disciplinary committee meeting was already underway on Wednesday evening, FIFA spokeswoman Delia Fischer said.
A day after he tangled with defender Giorgio Chiellini, Suarez was coping well, according to the Uruguay football federation president.
The bite, just before Uruguay scored the clinching goal to eliminate the four-time champion Italians, will now test FIFA president Sepp Blatter's often-stated commitment to "fair play, discipline, respect."
Blatter, who was in the crowd for the Uruguay-Italy match at Natal, has pledged a zero tolerance for the darker side of the game.
Many are questioning where that leaves a player like Suarez, who has a history of disciplinary problems including separate bans of seven and 10 matches for biting opponents in the Netherlands and England.
"When he falls, several substitutes insult him on the ground and some members of Italy's staff even came out of the bench to try to hit him," Valdez said, suggesting FIFA could investigate Italy.
Uruguay also will cite Brazil star Neymar getting only a yellow card in a clash with a Croatia player, Valdez said. Uruguay federation board member Alejandro Balbi, who is Suarez's lawyer, blamed European media reporting.
Suarez's teammate Diego Lugano agreed.
"The British media has a vendetta against Suarez, and everyone knows that," he said. "It's obvious the vendetta sells newspapers in England, otherwise you wouldn't be here. Uruguay and Italy played yesterday. On Saturday Uruguay plays Colombia, I don't know why there's a British journalist asking about Suarez.
