What happened: The Arizona Cardinals named rookie Carson Beck as their starting quarterback for Week 10 against the Los Angeles Rams. The move formalizes the transition under center after Beck was expected to start following Arizona's Week 9 offensive struggles.

Why it matters: Arizona turns to the rookie passer seeking an offensive spark after falling 17-3 to the Seattle Seahawks on Sunday. The Cardinals now hand the offense to their third-round selection against a Los Angeles team fresh off a 20-13 victory over Washington.

What to watch: Beck makes his first career NFL start on Sunday when Arizona hosts the Rams in an NFC West divisional matchup.
