What to know about new rules and technology behind FIFA World Cup’s most contentious calls

ATLANTA: (Jul 13)  It was another game-changing moment at the World Cup that had more to do with television replays in a room far away than a moment of brilliance on the field.

The sending off of Switzerland’s Breel Embolo in Saturday’s quarterfinal game against Argentina was the latest call that may have left fans scratching their heads, not least because of the confusing name of the newly implemented law that swung the match.

It is called the “mistaken identity” rule. Yet, technically, Embolo was not shown a second yellow card — resulting in a red — for a case of mistaken identity. It was because the referee Joao Pinheiro did not see in real time that the forward had simulated a foul under a challenge from Argentina’s Leandro Paredes.
