Football disciplinary chiefs gathered evidence against Luis Suarez on Wednesday as calls mounted for the Uruguay star to be kicked out of the World Cup after his latest biting storm.

The Liverpool striker shocked the footballing world when he sank his teeth into Italian defender Giorgio Chiellini during Uruguay's 1-0 victory over the Azzurri on Tuesday.

Suarez, banned twice before for biting opposing players, could be expelled from the tournament if found guilty.

Suarez and Uruguayan officials have until 5:00pm (2000 GMT) to submit evidence to a disciplinary panel set up by football's governing body FIFA.

"The disciplinary committee is working to get a decision as early as possible," FIFA spokeswoman Delia Fischer said when asked if a decision would likely be made before Uruguay's last 16 match against Colombia on Saturday.

Fischer would not speculate on the possible terms of any punishment, although she confirmed Suarez's prevoius offences could be taken into account.

"The disciplinary committee can take all elements into account as it deems necessary," she said.

While Suarez had "a right to be heard", he was not expected to travel to Rio from Uruguay's training base to address any disciplinary hearing, Fischer said.

Suarez was nowhere to be seen early Wednesday as his Uruguay team-mates trained in Natal amid the raging controversy.

Suarez, who plays in the English Premier League for Liverpool, is one of the world's biggest stars, and could theoretically be banned for up to 24 games under FIFA rules.

Fischer declined to say whether any potential punishment of Suarez could extend to club football as well as international football.

"It's the disciplinary committee which decides the scope of any potential sanctions," she said.

Suarez has already received long bans for biting during his club career as well as racially abusing Manchester United player Patrice Evra during a game in 2011.

The latest flashpoint occurred towards the end of Uruguay's clash with Italy.

Replays showed Suarez biting Chiellini's shoulder as the two players made contact in an off-the-ball incident.

Chiellini angrily remonstrated with Mexican referee Marco Rodriguez, pulling his shirt off his shoulder to show red marks on his neck.

Afterwards, Chiellini told Italian television: "He bit me, it's clear, I still have the mark."

Suarez sought to play down the incident in comments to Uruguayan television, claiming Chiellini had barged him.

"There are things that happen on the pitch and you should not make such a big deal out of them," Suarez said.

However the damning video evidence drew almost blanket condemnation on Wednesday across the globe, with many stating that Suarez required professional help.

"This is behaviour that's happened two times (before). You cannot justify it. I seriously think he needs help," said Everton manager Roberto Martinez.

Former Liverpool striker Robbie Fowler admitted he was "flummoxed" by the case and said the Anfield club should now seek to sell Suarez.

"You can't defend him," Fowler said. "I love him as a player, but you cannot condone what he has done."

Gordon Taylor, the head of England's players union the Professional Footballers' Association, expressed dismay over the incident.

"It was just so disappointing really," Taylor said.

Press commentators called for FIFA to impose a lengthy suspension.

"There is a case for a lengthy worldwide ban that sends an unmistakeable signal that talent can never justify the kind of behaviour that, in other circumstances, might bring a man before a judge for common assault," wrote columnist Matthew Syed in Britain's The Times.

Uruguayan daily El Observador said the incident was "the return of Suarez's madness." Suarez had tried to improve his image after the earlier bans, it said, but "against Italy the evil version of Suarez reappeared."

The controversy overshadowed the footballing action on Tuesday.

As Suarez awaits his fate, Lionel Messi, will hope to celebrate his 27th birthday a day late with another eye-catching performance for Argentina against Nigeria later on Wednesday.

Nigeria, though, will be seeking to make up for the disappointment of the Ivory Coast's elimination and give Africa something to smile about with a draw probably being good enough for them to progress.

However, a heavy defeat and an Iranian win over pointless Bosnia-Hercegovina could cost the African champions their place in the last 16.
