A Jan. 28 women's college basketball game between Florida State and Duke was played with a men's basketball for the first half.
Blue Devils head coach Kara Lawson sounded off about the incident while speaking to reporters after Thursday's win over Pittsburgh.
"This would never happen in a men's game. This would never happen," she said. "It's embarrassing for our sport."
Per Wilson, the official ball used in women's college basketball has a circumference that is one inch smaller and weighs two ounces less than regulation men's ball.
It's not clear how the mix up happened, though Lawson did note some of her players were "complaining about the ball" throughout the first half of the Florida State game.
