Brock Purdy Faces Seahawks' Top Defense in Week 5 Showdown

In Week 5 of the 2026 NFL season, San Francisco 49ers quarterback Brock Purdy will confront the Seattle Seahawks' defense at Lumen Field. Purdy has led his team to a 4-0 start, achieving a unique milestone by being the only quarterback in NFL history to begin a season with four wins while allowing one or fewer sacks, fumbles, or interceptions combined.

Purdy currently leads the league in passer rating, passing success rate, and expected points added per dropback, while co-leading in passing touchdowns. However, he will be challenged by the Seahawks, who boast the top defense in the league, allowing the fewest yards per play this season.

The Seahawks have previously dominated matchups against the 49ers, winning decisively in their last two encounters. This includes a 41-6 victory in the NFC divisional round, marking one of the most significant playoff wins in franchise history. As both teams prepare for this critical clash, the effectiveness of Purdy's offense against the Seahawks' pressure-heavy defense will be crucial.
