Sauerbrunn is one of several injured American players to miss the tournament, which kicks off July 20 in Australia and New Zealand, after attacker Mallory Swanson went down with a knee injury in April.

Midfield stalwarts Sam Mewis and Catarina Macario are also sidelined for the holders.

Sauerbrunn, 38, is one of the team's longest-standing players with 216 international appearances. She helped the Americans to World Cup titles in 2015 and 2019. Her most recent international appearance was a friendly against Ireland in April.

Head coach Vlatko Andonovski is set to announce his 23-player squad imminently and reports said he informed players Thursday of whether he planned to include them.
