Referee body cameras made their debut in the NWSL at the weekend ahead of being rolled out at the World Cup this summer. Multiple leagues around the world have already featured the technology, which provides viewers with a first-person view of a match's key moments. The move comes after FIFA confirmed that it will also use the cameras during the men's World Cup, which will be co-hosted by the USA, Canada and Mexico this summer. And its appearance in the NWSL at the weekend provided encouragement ahead of this summer's showdown, as many fans welcomed the addition. FIFA allowed the cameras to be used at the Club World Cup last year, with the governing body saying that the results had 'gone beyond our expectations.'
