SANTA CLARA, Calif. -- In the dress rehearsal for the regular season, the San Diego Chargers played solid against one of the powerhouses of the NFC West, the San Francisco 49ers, in a 21-7 loss Sunday afternoon at Levi’s Stadium.

San Diego’s starters played into the second quarter and led 7-3 before they were taken out on both sides of the ball. Defensively, the Chargers had their best effort of the preseason, with the first unit limiting San Francisco’s offense to 69 total yards on four drives.
