What happened: UCF will start Keyone Jenkins against No. 2 BYU on Saturday, per ESPN's Pete Thamel. Alonza Barnett III remains sidelined by a lingering hamstring injury that has kept him out five straight games. Coach Scott Frost said the James Madison transfer is making progress while working through mental reps on the sideline.

Why it matters: The homecoming game brings the highest-ranked opponent ever to visit Orlando, with undefeated BYU elevated after upsetting Notre Dame. Jenkins has developed from fill-in to record setter after Frost and Steve Cooper reshaped the passing plan around short and intermediate throws. The matchup tests UCF against a top-two team for the first time since a 35-3 loss to Texas in 2009.

What to watch: UCF hosts BYU on Saturday at Acrisure Bounce House. Barnett's return timeline hinges on continued progress in practice beyond homecoming.
