A fourth-quarter drive by San Francisco 49ers quarterback Brock Purdy produced the points that lifted his team to a 32-29 victory over the Seattle Seahawks, ending a stretch of 371 days without a home defeat for Seattle.

That 5-0 mark represents the third occasion San Francisco has reached an unbeaten start of that length under Kyle Shanahan, with each of the two previous instances extending deep enough into the calendar to include a February postseason appearance.

Between the two sides, seven turnovers changed hands and personal fouls accumulated across multiple stoppages. Linebacker Dre Greenlaw of San Francisco was removed from the contest by officials after a flag brought play to a halt.

For three quarters, neither attack found the space to build momentum, the match staying tight until the final period loosened its grip on the game. With the 49ers trailing by five points, Purdy orchestrated a methodical 12-play march covering 74 yards that ended with a 7-yard scoring throw to Mike Evans.

A targeting pass from Purdy found Evans once more, the 2-point conversion landing cleanly to lift San Francisco into a 29-26 lead. Following a Seattle field goal, San Francisco put together an eight-play, 43-yard possession that set up a 44-yard field goal — the one that ultimately decided the outcome — while Shanahan noted afterward that his quarterback had navigated a performance marked by both struggles and composure to deliver the win.

On the Seahawks' final drive, the offense fell short of converting a fourth-and-10, with questions lingering over whether receiver Cooper Kupp had stretched the ball far enough to move the chains on that play.

Facing a defense that ranked second across the league in expected points added per play, Purdy converted a pair of early turnovers into scoring opportunities and then directed two more touchdown drives as the fourth quarter unfolded. Four receivers from the San Francisco roster had been placed on injured reserve by the time Sunday arrived. Samuel and Cowing both left the field with injuries, while Shanahan pointed to the reserve players who filled in, noting that the team's depth extended well beyond its better-known contributors.

Evans hauled in seven receptions for 113 yards and a touchdown on the day — his most productive receiving output of the season — while also converting the two-point attempt, after which Purdy described him as a player he turns to with confidence at quarterback, and Evans himself told a broadcaster post-game that the contest had unfolded as a hard-fought battle from the start.

Purdy's passing line on the day read 19 completions from 29 attempts, 189 yards, two touchdown throws, and one interception, while he told reporters afterward that both teams had demonstrated their caliber, with his own side matching what the opposition brought. Through five weeks of play, his passing ledger showed 13 touchdown completions against just a pair of interceptions. Of all the outings he logged this season, only the one on Sunday fell below a passer rating of 100, with his mark settling at 92.5.

Of San Francisco's five victories, three have come against opponents with winning records, and the team's point differential leads the entire NFL. Of those victories, a pair came at the expense of divisional opponents — Seattle and the Los Angeles Rams.
