A white card was shown for the first time ever in a football match in Portugal on Saturday.

Red and yellow cards for fouls and misdemeanors have been an integral part of the sport for decades, but Portugal has introduced a white one as part of a series of new initiatives in the country, which also includes increased stoppage time and concussion substitutes.

Referee Catarina Campos brandished the card - shown to recognize and encourage fair play - during a women's cup clash between Sporting Lisbon and Benfica in Lisbon at the weekend in a first for the game.
