FIFA called for fair play on Monday when discussing Arjen Robben, but declined to take any retrospective action for the player’s dive or subsequent comments after the Mexico-Netherlands clash.
FIFA spokeswoman Delia Fischer said its disciplinary committee only "will look into serious infringements."
"We ask the players to play in the spirit of fair play," Fischer said. "It's up to the referees to manage a match."
Asked if he feared disciplinary action from FIFA, Robben said: "Not at all. Why?"
Robben's fall in the penalty box earned the penalty which substitute Klaas Jan Huntelaar converted in the fourth minute of stoppage time.
It ensured that the Netherlands will play Costa Rica in the quarterfinals on Saturday in Salvador.
The Robben incidents reignited a debate on diving, flopping and falling that began in the opening match of the tournament — a subject which seems to unite fans in anger and players in accepting it is part of the game.
On June 12, Brazil forward Fred won a penalty by falling under minimal contact from a Croatia defender. His action created the chance for Neymar to score the spot-kick, and take a 2-1 lead in an eventual 3-1 win.
Croatia's coach Niko Kovac did not blame Fred for falling, instead turning his anger on Japanese referee Yuichi Nishimura for awarding the penalty.
"I think we have to be realistic with each other," Robben said, when asked if players' views of diving controversies differ from fans and media.
