What happened: BYU hosts Arizona on Saturday after freshman receiver Legend Glasker scored three touchdowns on his first four collegiate touches against Utah Tech. Arizona quarterback Noah Fifita will challenge a BYU defense missing safety Raider Damuni with a lower-leg injury.

Why it matters: The matchup offers an early measure of BYU's defense against a proven Big 12 passer and tests whether Glasker can remain effective against stronger competition. Arizona opened the season by holding Northern Arizona to nine rushing yards and fewer than 200 total yards.

What to watch: Watch how BYU handles Fifita's arm and whether Arizona's secondary limits Glasker's downfield opportunities.
