Lucas Oil Stadium was a sea of cardinal and crimson as Ball State took on Indiana, eventually upsetting the Hoosiers 27-20.
Before the game, sophomore Connor Bailey said he wasn't sure how the game will turn out. For him, it seemed like anybody's guess.
"I just hope we put up a fight, even if we lose," he said. "But I hope we win."
Bailey said he hoped the Cardinal fans could out-cheer the Hoosiers, but he'd rather see a victory reflected on the score board.
"Hopefully we just win and let the score do the talking," he said.
Ball State was down 7-0 after the first quarter but regained the lead going into the fourth quarter, securing a win at 27-20.

Ally Doerner, a senior elementary education major, said she came to Indianapolis Friday night with two of her friends, and she had high expectations for Ball State.

She got her wish Saturday night.
Blake Hall, a sophomore chemistry major at Anderson University and a Muncie native, said he was looking forward to another season of Ball State football.
