More than 40 of the world's top female soccer players are preparing to sue FIFA and the Canadian Soccer Association in a Canada court next week after the two organizations missed a Friday deadline to reconsider staging next summer's Women's World Cup in Canada on artificial turf fields, a source told ESPN.

The suit argues that forcing them to compete on turf and not grass -- the surface every men's World Cup since 1930, including the 2014 tournament in Brazil, has been played on -- amounts to gender discrimination, which violates Canadian law.

The claim is to be filed in the human rights tribunal of Ontario. If FIFA and the CSA, which is based in Ottawa, Ontario, one of six host cities for the event, don't reverse course, the trial would likely take place in November, according to Hampton Dellinger, lead attorney for the players.
