Referee Sandro Ricci, from Brazil, shows a yellow card to Paraguay's Richard Ortiz after he fouled Argentina's Sergio Aguero (right) during a Copa America semifinal soccer match at the Ester Roa Rebolledo Stadium in Concepcion, Chile, on June 30, 2015. South American players are known for their vivid complaints and have long enjoyed more leeway when interacting with referees, especially compared to leagues in Europe, and now Brazil wants to put an end to that.
