Rivaldo could face both a fine and a ban after Fifa confirmed they would study video evidence of the Brazilian's clash with Turkey's Hakan Unsal.
The Barcelona playmaker was accused of play-acting, after he clutched his face in agony after Unsal kicked a ball at his legs as he was preparing to take a corner during their 2-1 victory on Monday.
Unsal received a red-card leading to boos of derision from the crowd as they watched the incident being replayed on the giant screens in the stadium.
"We have gone into the World Cup making it clear there will be a clampdown on simulation, which is Fifa-speak for cheating," said Fifa spokesman Keith Cooper.
