Cardinals vs. 49ers live updates, score: Defense, special teams have SF in action at halftime

Brock Purdy knows a thing or two about going from late-round draft pick to superstar quarterback — and Tom Brady knows it too.

The Niners will look to return to a winning record despite missing star RB Christian McCaffrey, who is sidelined indefinitely with Achilles tendonitis in both legs. On the other hand, the Cardinals are looking for a needed rebound after last week’s blowout loss to Washington.
