It wasn't pretty, but it counted, as the San Francisco 49ers picked up a 17-13 away win over the Seattle Seahawks on Sunday.

Quarterback Brock Purdy, fresh off a five-year, $265 million extension, had a lot to prove heading into Seattle — with mixed results. Mike Macdonald's Seahawks defense was in full force, picking off Purdy twice; there was also a pair of missed field goals from Jake Moody that made the final drive do-or-die.

But the 25-year-old quarterback got it done in the end. With less than two minutes remaining in the game, down three points, on third-and-three, Purdy overcame the Seahawks' pressure to scramble far out of the pocket.

His throw to the end zone was risky, with cornerback Tariq Woolen hovering near Jake Tonges, Purdy's target. But though Woolen got his fingers on it, Tonges was the one who came down with the ball.

On the drive before, Macdonald had opted to go for a field goal on fourth-and-one instead of going for it. The Seahawks took a 13-10 lead with Jason Myers' kick, and turned things over to the defense to get it done. But Purdy had a different idea.

After the 49ers took the lead, Seattle had about a minute and a half to reach the end zone. And here, Purdy got an assist from defensive end Nick Bosa, who shoved Abe Lucas right into Sam Darnold's throwing arm, and smothered the ball after it popped out.
