The Bayern Munich star was felled for a stoppage-time penalty - converted by Klaas-Jan Huntelaar - as the Dutch secured a last-gasp 2-1 win over Miguel Herrera's side to reach the quarter-finals.
Costa Rica stand between the Dutch and a spot in the final four, but fears were raised when Robben admitted diving earlier in the Mexico game in his post-match interviews.
When asked if he expected to be punished, Robben said: "No, not at all, why?
"I was not afraid, no. I am an honest guy. It had no influence on the game.
"I don't change myself. That's my personality.
"I think it's good. I apologised for one stupid action, but it didn't have an influence in the game.
"We had two clear penalties, one was given. That is it. I don't think we should talk about it any more."
