The 5 foot 4 defensive tackle didn't play during the game. She's a junior, and she isn’t a starter. Plus, the game was a nail-biter before the Knights eventually pulled out a 22-18 victory over the Engineers.
But for some, Jacey's playtime was less important than the fact that there was a girl on the team at all.
"Whether she plays or not, she's making history in this game," said her mother, Rosemary Lee. "She's the first girl standing in this stadium with the team. I'm so proud."
Jacey still ran out with the boys, dressed in the same gray uniform and bright orange helmet. She stood with her teammates on the sidelines to cheer during important plays. And she shook hands with all the Knights after the heartbreaking loss.
That was enough to break barriers, said some in the crowd. Jacey started playing football for Poly as a freshman, and was named JV captain the next year. School officials said she's the first girl to make the varsity squad.
Toria Thornes, 41, graduated from Poly in 1994. She can't imagine any of her female classmates being so bold as to sign up to play varsity football.
"Now, if you want to play on the team you can actually play," she said. "She's showing that girls can do it, too."
She turned to her six-year-old daughter, Londyne, who sat beside her in the stadium.
"It shows you that you can do anything you want to do, right?" Thornes asked her.
Londyne stopped eating her dip-in-dots for a moment and smiled. "Yes!" she said.
