Sam Gordon, a football player who went viral on social media after her father put her highlights on YouTube, lost her bid to have Utah school districts create football teams for girls.

U.S. District Court Judge Howard Nielson ruled Monday that Utah school districts aren’t legally required to create a separate sport for girls interested in playing football because girls who want to play can play on teams usually filled by boys.

However, the judge understood that schools and coaches should do more to encourage girls to put on the pads and helmets and that there may not be enough enthusiasm to keep such a league running.

Gordon, 18, argued she believed there were plenty of girls interested in playing football when she started an all-female league six years ago with her father called the Utah Girls Football League. The league is still active.

Nielsen disagreed, saying there was no district policy that discouraged girls from playing on the boys team and that districts were concerned whether there would be enough girls within the district boundaries to form all-girls teams.

"The districts will continue to strive to expand opportunities for all students and to ensure equal opportunities for male and female students in athletics and activities," Assistant Utah Attorney General Rachel Terry, who represented the districts, said in a statement.

Brent Gordon, Sam’s father and an attorney, said his daughter will look to continue to expand football opportunities for Utah girls.

"We appreciate the Judge’s efforts to have this trial during the pandemic so that the girls’ stories could be told and voices heard," he said in a statement. "Those voices will continue until equality in athletics is reached in Utah and across the country."
