Seahawks Crush 49ers 13-3, Clinch NFC No. 1 Seed With Dominant Defensive Performance
Seattle’s “Dark Side” defense holds San Francisco to 173 total yards, securing franchise-record 14th win and first-round playoff bye
SANTA CLARA, Calif. — The Seattle Seahawks completed their remarkable turnaround season Saturday night with a commanding 13-3 statement victory over the San Francisco 49ers at Levi’s Stadium, clinching the NFC West title and securing home-field advantage throughout the playoffs as the conference’s No. 1 seed.
In a game that had everything on the line — division championship, top playoff seeding, and first-round bye — the Seahawks’ elite defense suffocated one of the NFL’s hottest offenses, holding San Francisco to a season-low 173 total yards in what became a defensive masterclass under head coach Mike Macdonald.
The win marks Seattle’s franchise-record 14th victory of the season, improving their record to 14-3 and capping a seven-game winning streak that has them peaking at precisely the right time. The 49ers (12-5) saw their six-game winning streak snapped and will now hit the road as either the No. 5 or No. 6 seed in next weekend’s Wild Card round.
“All the things that we’ve been working at since we walked in the door, especially this year, are coming to life,” said Macdonald, whose second-year team is now 20-5 over their last 25 games. “I’m just incredibly proud of them. They played incredibly hard, they played together, they played complementary football.”
Victory Cigars and Historic Celebrations
Smoke-Filled Locker Room Marks Franchise Milestone
Pro Bowl defensive lineman Leonard Williams savored the moment in a smoke-filled locker room, where teammates celebrated with victory cigars — a tradition reserved for the franchise’s biggest victories.
“The victory cigars were pretty awesome,” said Williams, an 11-year veteran who’s never experienced this level of success. “I couldn’t really breathe in there at one point, but it didn’t really matter. My excitement and joy was taking over the smoke in my eyes and not being able to breathe. It was just beautiful to see my team celebrating.”
The emotional display reflected the significance of Seattle’s achievement: their first NFC West crown since 2020, a franchise-record for regular-season wins, and the fourth time in team history clinching the conference’s No. 1 seed — and in each of the previous three instances, they advanced to the Super Bowl.
“Dark Side” Defense Delivers Suffocating Performance
49ers Record Lowest Yardage Under Kyle Shanahan
The Seahawks defense, which entered the game allowing the second-fewest points in the NFL, faced a daunting challenge against a San Francisco offense that had averaged an eye-popping 42.3 points and 455.3 yards per game throughout December — exploding for at least 37 points in each of their previous three games.
Mike Macdonald’s defensive unit answered emphatically.
San Francisco managed just 173 total yards — their lowest output under head coach Kyle Shanahan since he took over in 2017. The previous low was 191 yards in a 2024 game against the Los Angeles Rams.
The 49ers failed to record a single first down in the entire opening quarter, were held to just nine first downs for the game, and converted only 2-of-9 third-down attempts while Seattle’s defensive front sacked quarterback Brock Purdy three times and hit him eight times throughout the night.
“We all have respect for the Legion of Boom, but I feel like we deserve some recognition at this point, too,” Williams declared, referencing Seattle’s legendary 2013-14 defense. “We call ourselves the Dark Side.”
Game-Sealing Interception Crushes 49ers’ Comeback Hopes
The game’s pivotal moment came early in the fourth quarter when linebacker Drake Thomas made a spectacular red-zone interception at Seattle’s 3-yard line that effectively ended any hopes of a San Francisco comeback.
On the 49ers’ best offensive drive of the game — their first time reaching the red zone all night — Purdy attempted a pass intended for Christian McCaffrey. The ball was tipped at the line by defensive end Boye Mafe, bounced off McCaffrey’s hands, and Thomas somehow managed to secure the deflection.
“It’s a play I have to make, absolutely have to make,” McCaffrey said afterward. “I expect nothing less but to make that play and it’s completely on me.”
ESPN cameras caught 49ers General Manager John Lynch in his suite expressing visible disbelief at yet another momentum-killing play by Seattle’s defense.
Ground Game Powers Seattle’s Ball-Control Offense
Walker and Charbonnet Combine for 171 Rushing Yards
While the defense grabbed headlines, Seattle’s running back tandem of Kenneth Walker III and Zach Charbonnet controlled possession and dictated tempo with a punishing ground attack.
Walker rushed for 97 yards on 16 carries, while Charbonnet added 74 yards on 17 carries and provided the game’s only touchdown — a 27-yard scamper in the first quarter that put Seattle ahead 7-0.
The Seahawks finished with 180 rushing yards — more than the 49ers’ entire offensive output and their second-highest rushing total of the season.
The most crucial play came facing third-and-17 from Seattle’s own 25-yard line with 3:48 remaining in the third quarter. Walker broke free for a 19-yard gain to extend the drive, which culminated in a Jason Myers 31-yard field goal that gave Seattle a commanding 13-3 lead with 14:15 remaining.
Sam Darnold Manages Game Efficiently
Quarterback Sam Darnold didn’t need to be spectacular, completing 20 of 26 passes for 198 yards with zero turnovers — exactly what Seattle’s defense-first approach required.
The performance was particularly meaningful for Darnold, who became only the second quarterback after Tom Brady to win at least 14 games in consecutive seasons with different teams. Darnold went 14-3 with the Minnesota Vikings last season under Kevin O’Connell, who won NFL Coach of the Year.
“It feels awesome, the fact we were able to do what we’re grounded in, which is run the ball and play defense,” said center Jalen Sundell, who brought the celebratory cigars to the locker room.
Pro Bowl wide receiver Jaxon Smith-Njigba led Seattle’s passing attack with six receptions for 84 yards.
Historic Playoff Path Opens for Seattle
Fourth No. 1 Seed Brings Super Bowl Expectations
This marks the fourth time in franchise history Seattle has clinched the No. 1 seed, and the historical precedent is remarkable:
- 2005 season (Mike Holmgren): Reached Super Bowl XL
- 2013 season (Pete Carroll): Won Super Bowl XLVIII with Legion of Boom
- 2014 season (Pete Carroll): Reached Super Bowl XLIX
In all three previous instances, the Seahawks advanced to the Super Bowl when earning the conference’s top seed.
With Levi’s Stadium hosting Super Bowl LX on February 8, 2026 — just five weeks away — Macdonald’s team hopes to return to the same venue where they just secured the conference’s top seed.
“That’s definitely a point of pride that we can have at least one home playoff game in front of the 12s,” Macdonald said. “They’ve been dynamite this year. They’ve been absolutely just incredible. We’re really excited to stay home.”
Lumen Field Playoff Advantage
The Seahawks’ home-field advantage at Lumen Field is legendary. The team has won 10 consecutive home playoff games played in front of fans, with their only home playoff loss since the 2005 season coming during the 2020 season when fans were restricted due to COVID-19.
“It’s huge to be able to play in front of the 12s,” Darnold said. “It’s unlike any other stadium in terms of how loud it can be and how tough it can be for the other offense. We’re really looking forward to being at home for the playoffs.”
Seattle finished 6-2 at Lumen Field this season, winning their final five home games. The 12th Man faithful are expected to create a playoff atmosphere that could prove decisive in January’s divisional round.
First-Round Bye Provides Crucial Recovery Time
The Seahawks will enjoy a first-round bye and are expected to have left tackle Charles Cross and safety Coby Bryant back from injuries for their divisional-round game, scheduled for either January 17 or 18.
Seattle will host the lowest remaining seed from Wild Card weekend, with potential opponents including the 49ers (if they advance), Carolina Panthers, or Tampa Bay Buccaneers.
Mike Macdonald’s Remarkable Turnaround
From 10-7 Disappointment to 14-3 Dominance
Just one year ago, the Seahawks finished 10-7 in Macdonald’s debut season and agonizingly missed the playoffs due to tiebreakers — eliminated before Week 18 even kicked off. That pain hung over Seattle as motivation throughout 2025.
Macdonald, the 37-year-old defensive mastermind who replaced legendary coach Pete Carroll after the 2023 season, has orchestrated one of the most impressive two-year coaching starts in NFL history.
Macdonald’s Career Coaching Record:
- 2024 season: 10-7 (missed playoffs)
- 2025 season: 14-3 (NFC West champions, No. 1 seed)
- Overall: 24-10 (.706 winning percentage)
- Last 25 games: 20-5 (.800 winning percentage)
His 24-10 record through two seasons represents the best two-year start to a coaching career in Seahawks history, surpassing Chuck Knox’s 21-11 mark from 1983-84.
Franchise Records Shattered
Under Macdonald’s leadership this season, the Seahawks have rewritten the record books:
- Most wins in a season: 14 (previous: 13)
- Most road wins in a season: 8 (tied franchise record)
- Consecutive road wins: 10 straight (franchise record)
- Point differential: Plus-191 (best in franchise history and NFL-best in 2025)
- Points scored: 483 (most in franchise history)
- Road record over two seasons: 15-2 (best in NFL)
“We’re here today as number one seed because of Mike,” linebacker Ernest Jones IV said. “He’s a defensive wizard.”
Coach of the Year Buzz Building
National media outlets, including ESPN and Sports Illustrated, have identified Macdonald as a leading candidate for NFL Coach of the Year honors.
ESPN’s Bill Barnwell noted: “Macdonald is a defensive wizard. For the second year in a row, the Darnold-led offense is just on the right side of average, as the Seahawks are 14th in the league in EPA per play on offense. They finished just behind the Texans for second in EPA per play on defense.”
Barnwell highlighted how Macdonald has maximized aging veterans like Ernest Jones, DeMarcus Lawrence, and Leonard Williams while developing young stars such as Byron Murphy, Devon Witherspoon, Ty Okada, and Drake Thomas.
Pete Carroll Comparison Grows Starker
The contrast between Seattle and Macdonald’s predecessor couldn’t be more dramatic.
Pete Carroll, who coached the Seahawks from 2010-2023 and won Super Bowl XLVIII, moved on to the Las Vegas Raiders as head coach. In his first season in Las Vegas, Carroll’s Raiders finished 3-14 — the worst record in the NFL — and he was fired Monday, becoming one of four head coaches from the 2024 hiring class already dismissed.
Meanwhile, Macdonald has transformed Seattle into a juggernaut, with reports emerging Monday that other teams want to interview his offensive coordinator Klint Kubiak for head coaching positions — a clear sign of the respect Macdonald’s program has earned league-wide.
49ers Face Uphill Wild Card Battle
San Francisco Drops to No. 5 or No. 6 Seed
The loss drops the 49ers to either the No. 5 or No. 6 seed in the NFC, depending on Sunday’s outcome between the Los Angeles Rams and Arizona Cardinals. If the Rams defeat Arizona, San Francisco will fall to the sixth seed and face an even more difficult road playoff path.
Brock Purdy struggled under constant pressure from Seattle’s defensive front, completing 19 of 27 passes for just 127 yards with one interception. He didn’t surpass 100 passing yards until the fourth quarter — a stark contrast to his recent dominance.
Christian McCaffrey was held to a mere 23 yards on eight carries and six catches for 34 yards — his lowest production of the season. George Kittle caught five passes for just 29 yards.
Injuries Hamper San Francisco’s Offensive Output
The 49ers played without Pro Bowl left tackle Trent Williams (hamstring) and receiver Ricky Pearsall, both sidelined with injuries. Head coach Kyle Shanahan deemed it “too risky” to play them in this contest, saving them for the playoffs.
Without Williams protecting Purdy’s blind side, Seattle’s pass rush dominated — a factor that could prove decisive if these teams meet again in the playoffs.
“Now we got to do it the hard way,” Shanahan said after the game, acknowledging the difficult road ahead for his injury-plagued team. “We’re ready for it. It would have been nice to have a home game here — or both home games — and get a bye. But it is what it is. This team’s been through a lot this year.”
Rivalry Reversed
The result represents a complete reversal from Week 1, when the 49ers defeated the Seahawks 17-13 in Seattle. The Seahawks have now won seven straight since that early-season setback.
Macdonald evened his personal coaching record against Shanahan at 2-2, though he quickly brushed aside the individual narrative after the game, choosing instead to spotlight his players and the process behind the turnaround.
What’s Next: Playoff Picture Takes Shape
Seahawks Rest While Competition Battles
Seattle will enjoy a first-round bye next weekend while the rest of the NFC playoff field battles through Wild Card weekend. The Seahawks will then host the lowest remaining seed in the divisional round at Lumen Field.
Possible divisional-round opponents (if they win their Wild Card games):
- San Francisco 49ers (12-5) — Revenge game opportunity
- Carolina Panthers (8-9) — NFC South champions
- Tampa Bay Buccaneers (10-7) — Wild Card team
- Los Angeles Rams or Washington Commanders (depending on results)
“The job’s not done,” Williams emphasized. “This is the closest team I’ve ever been on, the most winning season I’ve ever been on. But we have work to do.”
Message to NFC: The Road Runs Through Seattle
The Seahawks’ dominant performance sends a clear message to the rest of the NFC: the road to Super Bowl LX runs through Seattle, and this defense-first team is built for a deep playoff run.
With the NFL’s best point differential (plus-191), a suffocating defense allowing the second-fewest points in the league, and a ground-and-pound offensive identity that controls clock and tempo, the Seahawks possess the formula that historically succeeds in January.
“We have gotten here through our mentality of every single day,” Macdonald told his team in the locker room. “That’s what it’s going to take next week. Right now, it’s time to celebrate.”

The Bottom Line
In Mike Macdonald’s second season, the Seattle Seahawks have transformed from playoff disappointment to Super Bowl contender. Their franchise-record 14-win campaign, anchored by a dominant “Dark Side” defense and complemented by a ball-control offense, has them positioned for their first championship run since the Legion of Boom era.
With home-field advantage throughout the playoffs, a first-round bye for rest and recovery, and Super Bowl LX set for the same Levi’s Stadium where they just dominated the 49ers, the stars are aligning for Seattle.
History suggests the Seahawks should take this opportunity seriously: they’re 3-for-3 in reaching the Super Bowl when clinching the No. 1 seed, including their only championship in 2013.
The job isn’t done, but Saturday night’s statement victory over San Francisco proved the Seahawks are ready for whatever January brings.
The road to Super Bowl LX runs through Seattle. And the 12th Man couldn’t be happier.
