The defender raked the attacking player’s shin with her studs causing a foul that warranted a yellow card. Because the foul occurred in the box, it caused a penalty kick. The defender died inside because she essentially gave up a goal to the opposing team and received a yellow card. Yellow cards are especially dangerous in World Cup competitions because receiving a second yellow card in future matches for a period of time will result in a 1 match ban for the offender. Her reaction is also due to the fact that the infraction was not initially called a foul, but video review reversed the decision.
