Recap: Stalwart defense, late-game heroics give 49ers hard-fought 17-13 win in Seattle

The Seahawks then moved downfield quickly after two runs from Zach Charbonnet, an unnecessary roughness penalty on cornerback Deommodore Lenoir, and a 21-yard completion to Smith-Njigba. From there, the Seahawks moved inside the 5-yard line on a series of runs, then they were given a first down after cornerback Upton Stout was flagged for pass interference on a 4th-and-3 play from the 4-yard line. Charbonnet ran in from one yard out on the next play to tie the game at 7.

The offenses stalled for a bit after that as the two teams traded three-and-outs, then the 49ers punted back to the Seahawks after a five-play possession. After another three-and-out from the Seahawks, the 49ers took over at their own 34-yard line and got their offense moving again with back-to-back completions to McCaffrey followed by a third-down completion to wide receiver Jauan Jennings to move into Seahawks territory. Purdy then connected on a 25-yard pass to fullback Kyle Juszczyk to move inside the 20, then runs from McCaffrey and Purdy moved the ball inside the 10 and brought the second quarter to the two-minute warning. The drive stalled from there, forcing the 49ers to settle for a 27-yard field goal attempt from kicker Jake Moody, which hit the upright and fell no good with 57 seconds remaining in the half.

That proved to be enough time for the Seahawks to move back into field goal range, due in large part to a 22-yard completion to Smith-Njigba on the second play of the ensuing possession that moved the ball near midfield. A short completion to wide receiver Cooper Kupp followed by runs from Charbonnet and Darnold moved the ball to the 49ers' 30-yard line, after which the Seahawks took a 10-7 lead on a 48-yard field goal by kicker Jason Myers with two seconds remaining.

The 49ers held an advantage of 166 to 122 in total yardage at the half and held the ball for over 18 minutes, while Purdy out-passed Darnold 124 to 72. But with the missed field goal from Moody being the difference, the 49ers entered the locker room with their first halftime deficit of the season.

Second Half

Things started out well for the 49ers out of the gate in the third quarter, as a completion from Purdy to McCaffrey moved the ball to midfield. The tide turned quickly, however, as four plays later Purdy sailed a pass into the hands of linebacker Ernest Jones, who hauled in the interception and gave the Seahawks the ball at their own 29-yard line.

The defense answered the bell for the 49ers by holding the Seahawks to a three-and-out, then the 49ers took over at their own 25 after an 18-yard punt return by Skyy Moore . The 49ers churned their way downfield with a series of runs by McCaffrey and Robinson, then moved past the Seahawks 30-yard line on a 4th down conversion pass to tight end Luke Farrell. The 49ers faced a 4th-and-2 four plays later but elected to go for another field goal, this one from 36 yards. But this time the field goal was blocked by safety Julian Love, giving the Seahawks possession at their own 31-yard line after a recovery by linebacker DeMarcus Lawrence.

Once again, the 49ers' defense went on to bail their special teams out. The Seahawks moved across midfield following the blocked kick, then the defense came up with their first turnover of the day -- a forced fumble by defensive lineman Sam Okuayinonu that was recovered by rookie safety Marques Sigle on the first play of the fourth quarter.

The 49ers took over at their own 34-yard line and quickly moved into the red zone due in large part to a 14-yard run by McCaffrey followed by a 24-yard completion to Pearsall. After a 9-yard run from Robinson to get the 49ers over the 20-yard line, the 49ers faced another fourth-down decision after two negative runs by McCaffrey. On a 4th-and-2 from the 14-yard line, the 49ers decided not to leave things in the hands of their kicking game and converted with a pass to McCaffrey that moved the ball to the 8-yard line. But things imploded inside the 10 as McCaffrey was stopped for no gain, then after an incomplete pass in the end zone intended for Pearsall, a false start penalty on tackle Colton McKivitz, and an incomplete pass to McCaffrey, the 49ers had to turn back to Moody once more, this time from 32 yards. Moody split the uprights this time, tying the game at 10 with less than ten minutes to play.

The Seahawks took over at their own 37 after a 36-yard kick return by Cody White but quickly moved backwards after an eight-yard first down tackle-for-loss by Bosa on Smith-Njigba. A terrific broken up pass by cornerback Renardo Green followed by a failed hook-and-ladder attempt on third down led to another three-and-out from the Seahawks, giving the 49ers back with just over eight minutes remaining.

That opportunity was squandered, however, when Purdy floated an interception to cornerback Josh Jobe, which gave the Seahawks the ball back at their own 48-yard line. The Seahawks turned that interception into points but only a field goal as the 49ers defense held firm inside the 30, forcing a 4th and 1 at the 19-yard line. The Seahawks elected go for three instead of a first down and opened up a 16-13 lead after Myers connected from 37 yards.

The 49ers took over at their own 32 after a 24-yard return from Moore, then on the second play of the drive, Purdy found Pearsall for a monster gain of 45 yards to the Seahawks' 22-yard line . A two-yard completion to tight end Jake Tonges moved the clock to the two-minute warning, then Purdy found Tonges again for a nine-yard gain to the 11-yard line. A one-yard run and a six-yard catch by McCaffrey set up a 3rd-and-3 from the 4-yard line, then in improbable fashion, Purdy escaped the pass rush and lofted a pass into the hands of Tonges in the end zone, giving the 49ers the lead. Moody connected on the extra point, putting the score at 17-13 with 1:34 to play.

The Seahawks weren't about to go quietly. After starting at their own 35-yard line following a touchback, completions of 11 and 40 yards to Smith-Njigba put the ball at the 14-yard line. A penalty moved the ball up five yards, but then it was Bosa's turn to step up. Bosa pushed offensive tackle Abraham Lucas into Darnold, causing a fumble that Bosa recovered at the 16.

The fumble recovery was the last nail in the coffin for the Seahawks, who watched as the 49ers ran out the clock to take the win. The 49ers now stand at 1-0 after the victory, while the Seahawks were the lone NFC West team to open their season with a loss.
