What happened: Home fans stormed the field Saturday after the Knights defeated the second-ranked Cougars in double overtime. UCF played with Jenkins starting at quarterback while Barnett remained out, and recovered a blocked third-down kick during the game.

Why it matters: The defeat deals BYU a pivotal setback in the Big 12 race and national College Football Playoff positioning. UCF secured the upset despite relying on reserve quarterback depth against a top-two opponent.

What to watch: Sunday's national polls will determine how far BYU falls from the No. 2 spot, while UCF will evaluate Barnett's availability ahead of its next conference game.
