Players, mainly professional Americans playing in Europe, were chosen for the team on May 31, 2017. Players were promised full funding from the United States Federation of American Football, however, the funding was withdrawn just days before the competition and players had to provide their own transportation to Wroclaw. As a result, most of the team withdrew from the competition and were instead replaced by volunteers who were already in Europe at the time.[5] Most of the team arrived the day before their opening match vs the Germany national American football team. The Americans lost to Germany 13–14, in which was the first loss ever for a United States national American football team in international competition.
The U.S. won gold in women's lacrosse, beating Canada 11-8 in the final.[7] 2017 was the first year that the World Games included any version of lacrosse.[8]
