In a historic moment, a new type of card, the "white card," was introduced during a women's derby match between Benfica and Sporting Lisbon in Portugal. While the yellow and red cards have been a staple in soccer since the 1970 FIFA World Cup, this was the first time a white card was used in a game. The card was used when a fan in the stands felt ill at the end of the first half. The referee displayed the white card to both medical teams who rushed to the aid of the fan in recognition of their sportsmanship.
