FIFA vice-president, Jim Boyce says there will be an investigation into the biting incident of Uruguay striker Luis Suarez.
Liverpool striker Suarez faces being thrown out of the World Cup if he is found guilty of biting Giorgio Chiellini as Uruguay eliminated Italy to make their way into the knockout stages.
Boyce, said: "There is no doubt that Fifa must take this incident very seriously and take whatever action is deemed necessary.
"Luis Suarez is a fantastic footballer but once again his actions have left him open to severe criticism."
The maximum penalty it can impose is a 24-game, two-year ban, although in practice, the heaviest sanction it has ever taken was an eight-match penalty served against Italy's Mauro Tassotti for breaking Luis Enrique's nose in a match against Spain in the 1994 tournament.
This is the third biting incident to have disfigured Suarez's career. He was banned for seven games for biting the PSV Eindhoven defender, Otman Bakkal, while playing for Ajax and 10 for biting the Chelsea full-back, Branislav Ivanovic at Anfield in April last year.
