What happened: The Arizona Cardinals changed quarterbacks during Sunday's game and lost their starting running back to injury. Arizona withstood the backfield turnover to defeat the Dallas Cowboys 33-30.

Why it matters: Managing depth in the offensive backfield becomes critical following the in-game quarterback transition and running back injury. Securing the victory cushions Arizona in the conference standings as the offense adapts to personnel questions.

What to watch: Arizona will evaluate the starting running back's injury status and clarify the quarterback rotation ahead of practice this week.
