Riley Gaines says Target Center staffer tried to shut down her Sophie Cunningham sign

XX-XY Athletics owner Jennifer Sey discusses what girls faced for holding Sophie Cunningham signs at WNBA games on ‘Fox News @ Night.’

Minnesota Lynx coach Cheryl Reeve was permitted to wear a "Trans kids belong" shirt on the sideline during Sunday’s game against the Indiana Fever.

Fans throughout Target Center held signs supporting their favorite WNBA players.

But when Riley Gaines displayed a small sign reading, "Sophie, thank you — a girl mom," an arena staffer tried to make her put it down.

According to Gaines, the staffer told her the problem was that the sign contained Fever guard Sophie Cunningham’s name.

"I checked all the sign policies before I went in there," Gaines told OutKick. "I made sure it was like 11 by 17. That’s the sign size you could have. So, I got a ruler out. You better believe I was measuring it."

Gaines attended Sunday’s Fever-Lynx game to support Cunningham, who has faced intense criticism since publicly stating that women’s sports should be reserved for women.

Cunningham was loudly booed throughout Indiana’s 108-100 loss in Minneapolis, while Reeve used the game to make her opposing position clear.

ESPN’s broadcast highlighted Reeve’s shirt and encouraged viewers to listen to the Lynx coach’s previous comments on transgender athletes.

Meanwhile, a staffer inside the arena apparently decided Gaines’ simple message of support for Cunningham needed to disappear.

Gaines arrived at Target Center around 11:40 a.m. local time, approximately 20 minutes
