(AP Photo/Don Ryan, File)Players for the Portland Thorns and the North Carolina Courage knelt during the national anthem Saturday when the National Women's Soccer League opened the Challenge Cup tournament in Utah.
In addition to the anthem, the players knelt for a moment of silence before kickoff.
The league said Friday that it would play the national anthem before the Challenge Cup games and that it would support the players in whatever they chose to do.
The monthlong Challenge Cup opened Saturday with a pair of games at Zions Bank Stadium in Herriman, Utah.
Megan Rapinoe, who plays for OL Reign but opted out of the Challenge Cup, was criticized when she knelt at a NWSL game and a pair of national team games in 2016.
