 All of the tournament's venues had fields composed of artificial turf, which some players believe results in a higher risk of injuries to players.More than 50 players protested the use of the surface instead of grass on the basis of gender discrimination.They filed a lawsuit challenging FIFA's decision to play on artificial turf, claiming FIFA would never allow the men's World Cup to be played on "unsafe" artificial turf and thus the organizers had violated the Canadian Human Rights Act.
