San Francisco's No. 1 offense still looks shaky two weeks from the regular season, and the 49ers did just enough for their first preseason victory in a 21-7 win against the San Diego Chargers on Sunday.
There were tens of thousands of empty seats hours after an overnight 6.0-magnitude earthquake struck in the Northern California wine country near Napa. The quake affected some public transportation options to the new $1.2 billion stadium, which sold out last Sunday.
The patchy field is still hardly ideal, with visible lines where new sod was placed Friday after the initial turf failed to hold.
Phil Dawson kicked a 39-yard field goal at the 9:27 mark of the second quarter, ending an eight-quarter scoreless drought for the 49ers as they doubled their preseason total. Dawson added another from 28 yards a week after missing twice.
Backup Blaine Gabbert threw a 6-yard touchdown pass to Vance McDonald late in the first half for the 49ers' first TD of the preseason. That capped a drive in which Gabbert went 5 for 6.
Philip Rivers completed his first five passes and finished 9 of 10 for 85 yards and a touchdown. San Francisco's Colin Kaepernick was 6 of 12 for 59 yards.
With Rivers' outing and Peyton Manning's 12-of-14 performance in a 34-0 rout last Sunday, the new-look 49ers secondary allowed the past two starting quarterbacks to complete 21 of 24 passes for 187 yards and passer ratings of 120 or better.
San Francisco's offensive line had major problems protecting Kaepernick, who was hit hard four times in three first-quarter series.
Right guard Alex Boone has held out all offseason in hopes of a new contract with two years remaining on his previous deal, and he might now have some increased leverage.
Kaepernick lost a fumble when he got stripped and pounded by Corey Liuget, who beat left guard Mike Iupati. But the Chargers failed to score when Ryan Mathews was stuffed on fourth-and-1 from the 5 by Michael Wilhoite.
Kaepernick was hit again on his next pass attempt, then a fourth time during his third series.
An illegal block nullified Rivers' 25-yard touchdown pass to Mathews in the final minute of the first quarter. But Rivers connected on a 10-yard TD pass to Antonio Gates on the next play.
The Chargers outgained San Francisco 121-17 in the first quarter — but not without a cost.
Defensive tackle Kwame Geathers went down with a knee injury at the 7:09 mark in the first quarter, while center Nick Hardwick suffered a first-half neck injury.
San Francisco's Glenn Winston ran for a 27-yard touchdown in the fourth quarter against a Chargers defense that allowed five TDs rushing in a 41-14 loss to the Super Bowl champion Seattle Seahawks.
Kaepernick and Anquan Boldin spent extensive time testing their footing, working on routes and communicating during warmups on the new grass, which still featured divots and holes and isn't a permanent solution.
The 49ers have won the past five preseason meetings between the teams, who have faced off in the exhibition schedule every year since 1987. Neither showed much given they play here again in Week 16 on Dec. 20.
Craig Dahl started at safety for the 49ers in place of Antoine Bethea, held out as a precaution after last Sunday's concussion. Linebacker Patrick Willis made his first appearance of the preseason.
