A red card means trouble and controversy at the World Cup: Here's what to know‎

The Americans are seeing red over the most controversial and consequential red card so far in the World Cup. While the United States celebrated a 2-0 win over Bosnia-Herzegovina, fans and players were angry and frustrated by a second-half red card that sent off star striker Falorin Balogun. The penalty, called after the referee watched a video replay, ignited debate over whether it was too harsh and whether other players, most notably Argentina's Lionel Messi, have unfairly avoided similar punishment.
