FIFA said it would study the referee' s report and the match video.
"We are awaiting the official match reports and will gather all the necessary elements in order to evaluate the matter," FIFA spokeswoman Delia Fischer told AFP.
But other senior officials wasted no time in condemning the striker.
"There is no doubt Luis Suarez is a fantastic footballer but once again his actions have left him open to severe criticism," FIFA vice-president Jim Boyce told the BBC. "FIFA must investigate this incident very seriously and take whatever action is deemed necessary." AFP
