Purdy runs for a TD before Chargers backups roll past 49ers 23-12

SANTA CLARA, Calif. (AP) — Brock Purdy ran for a 5-yard touchdown during a brief tune-up for the season opener for San Francisco before the Los Angeles Chargers backups beat the 49ers 23-12 in the exhibition finale. The teams took different approaches in the final preseason game with San Francisco playing Purdy and several other starters for two drives, while the Chargers used almost exclusively second and third-string players. The game took place only a few hours after the Niners traded former quarterback of the future Trey Lance to Dallas for a fourth-round draft pick.
