Trey Lance’s return to the Bay Area led to three straight punts for the Los Angeles Chargers, who went on to lose 30-23 Saturday night to the San Francisco 49ers in the final exhibition game for both teams. Curtis Robinson returned a interception of DJ Uiagalelei 32 yards for the go-ahead touchdown with 6:06 remaining to give San Francisco the win. Lance played his first game at Levi’s Stadium since the 49ers traded him to Dallas two summers ago.
