Just before the bye, the 49ers looked shaky, yet they surged to a convincing win.
The 49ers outscored the Raiders 38-17 on Sunday, showcasing a stout defense.
San Francisco forced five turnovers, snatching three interceptions from Kirk Cousins and recovering fumbles by Brock Bowers and Michael Mayer.
Three long drives—each over a dozen plays—produced touchdowns and gave the 49ers a 21-10 halftime lead.
The momentum exploded early in the third quarter when Cousins tossed a pick‑six to linebacker Jaden Dugger, stretching the lead to 28-10. In my view, the defense stole the show.
Las Vegas answered with a 21‑yard touchdown catch by Brock Bowers, but subsequent fumbles by Mayer and Bowers stalled their comeback in the third quarter.
The Raiders surrendered a turnover on each of their final four possessions, five of their last six overall.
Purdy completed 17 of 25 passes for 232 yards, two scores and one interception, and added 40 rushing yards on seven carries before Mac Jones entered for garbage time.
Cousins went 22‑for‑32 for 216 yards, recording one touchdown and three picks, while Bowers hauled in seven catches for 111 yards and a score.
Ashton Jeanty’s ground game fizzled, managing just 25 yards on six attempts.
Can San Francisco keep this defensive dominance alive against Dallas?
The Raiders, who have lost five of their last six, will be back at home to face the Seahawks next Sunday.
