Brock Purdy threw four touchdown passes, with the first coming on a trick play, and the injury-depleted San Francisco 49ers held on for a 36-30 victory over the Arizona Cardinals on Sunday. San Francisco lost wide receiver Mike Evans to a rib injury in the first half and left tackle Trent Williams to a stinger in the second half, but still managed to hold on to start 3-0 for the third time in the last four seasons. The game began well for the Niners before the injuries started mounting and they found themselves in a tight game against the Cardinals (1-2), who have lost 22 of their last 26 games in the division.
