Switzerland defender Stephan Lichtsteiner has blasted the decision which saw Valon Behrami sent off against Chile.
The West Ham man saw red after catching Arturo Vidal with a raised arm during the first half of a 1-0 defeat for the Swiss on Monday.
The decision looked harsh, with little intent in Behrami's actions as he sought to fend off his man.
He will now be forced to sit out a crucial encounter with Honduras on Friday as a result, with Switzerland looking to book their place in the last 16 of the World Cup.
Lichtsteiner is disappointed that Ottmar Hitzfeld's side will be without the versatile Behrami, as he feels Vidal conned the referee into making a decision which could prove costly.
"Behrami may have used his hands and arms to defend the ball when he was attacked by several Chile players, but he certainly didn't hit or nudge Vidal," said the flying full-back.
"Yet he made the referee believe that Behrami must have hit him in the face."
Vidal admitted after the game that he was surprised to see a red card brandished, but that is of little consolation to the Swiss.
Lichtsteiner added: "Nice one. That's not of much use to our team now is it? Let me ask one question: Why do outstanding players like Vidal use cheap tricks like this?"
While Behrami's absence will undoubtedly be felt against Honduras, Switzerland are confident they have the strength in depth to cover the loss.
Goalkeeper Diego Benaglio insists they do not rely heavily on any one player, with their success built on an unbreakable team spirit.
"I could give the names of lots of people who could do the job," he said.
"That is one of the qualities of our squad. We do not depend on any particular players - we are a good, well-balanced team that knows how to score."
