San Francisco’s defensive front gave Sam Darnold fits twice this season, generating consistent pressure in both meetings, and an oblique injury that kept him from throwing a single pass since Thursday makes that pass rush the swing factor in Saturday’s NFC Divisional Round matchup at Lumen Field.
The third meeting between NFC West rivals arrives with familiar stakes and a familiar pattern. Both regular-season contests were physical, grinding affairs that never crossed 30 combined points.
Seattle took the more recent one, 13-3, to clinch the conference’s top seed. San Francisco answered with a gutty 23-19 Wild Card win at Philadelphia. Now the Niners must do it without George Kittle, whose torn Achilles ended his season in that Eagles game, and potentially against a quarterback who hasn’t tested his oblique since it flared up in Thursday’s practice.
Sam Darnold’s Oblique and the Seahawks’ Offensive Identity
Darnold told reporters there’s “close to a zero-percent chance” he won’t suit up Saturday. Head coach Mike Macdonald echoed that optimism Friday, saying the team is “really optimistic” about their Pro Bowl quarterback’s availability. But ESPN’s Adam Schefter reported Saturday morning that Darnold hasn’t thrown a football since the injury occurred during a routes-on-air period. He’ll test it in warmups before a final decision.

The injury matters beyond simple availability. Darnold’s left oblique affects his ability to drive throws, particularly on intermediate routes to his left. San Francisco’s defense, ranked 26th by PFSN’s Defense Impact metric (67.6, D+), has been vulnerable all season, but not against Seattle. The Niners held the Seahawks to 173 total yards in the Week 18 meeting, the fewest San Francisco has allowed under Kyle Shanahan. A compromised Darnold facing that same pressure-heavy scheme presents the cleanest path to an upset.
Seattle’s offensive line, ranked 17th by PFSN’s Offensive Line metric (72.0, C), has protection concerns even with a healthy quarterback. Without full torque on his throws, Darnold may need to lean even harder on Kenneth Walker III and Zach Charbonnet, who combined for 171 rushing yards in the Week 18 win. That ground game carried Seattle to the top seed, but expecting it to shoulder the entire offensive burden against a desperate 49ers front is a significant ask.
Drew Lock has taken first-team reps all week and would be ready if needed. Lock, who signed with the Seahawks in April 2025 after a year with the New York Giants, has 28 career starts but attempted just three passes during the regular season. Offensive coordinator Klint Kubiak expressed confidence in the backup, but Seattle obviously prefers Darnold, even at less than 100 percent.
PFSN projects Seattle with a 61.1% win probability against San Francisco’s 38.9%. The Seahawks sit atop the PFSN power rankings at No. 1 (83.9), while the Niners rank 10th (75.8). That gap is real. But the individual quarterback grades tell a more nuanced story: Brock Purdy ranks first at 92.1 (A-), while Darnold sits 13th at 78.7 (C+). A limited Darnold narrows that margin considerably.
The Special Teams Battle No One’s Talking About
Lost in the quarterback drama is the most evenly matched special teams showdown in the divisional round. San Francisco ranks third by PFSN (87.8, B+); Seattle ranks second (90.9, A-). In a game that figures to be tight and physical, both previous meetings saw total scores of 30 and 16, field position and hidden yardage could prove decisive.
Jason Myers has been money for Seattle all season, including a franchise-record six field goals in a Week 15 win over Indianapolis. Eddy Piñeiro’s field goal provided San Francisco’s only points in the Week 18 loss. If this game follows the pattern of the first two meetings, expect kickers and coverage units to matter.
The 49ers defense, despite its overall struggles, found something against Seattle’s offense specifically. They held Purdy to 127 passing yards in the regular-season finale, but they also stifled Darnold’s passing attack; he threw for under 200 yards in both meetings without a touchdown pass. That defensive blueprint exists. Whether a banged-up roster can execute it for 60 minutes on the road is another question.
Kittle’s absence looms large. In the Week 18 loss, he commanded significant attention from San Francisco’s targets before the offense stalled completely. Luke Farrell and Jake Tonges will absorb snaps at tight end, but neither offers Kittle’s combination of receiving threat and blocking prowess. The Niners ranked 4th offensively by PFSN (85.2, B) with Kittle; they’re a fundamentally different unit without him.
Fred Warner remains out with the ankle injury that’s sidelined him since Week 6. San Francisco opened his practice window this week with hopes of a return in the NFC Championship Game, but he won’t factor into Saturday’s equation. The compound effect, no Kittle, no Warner, road environment, rested opponent with a week of preparation, creates a challenging equation for Shanahan.
Seattle emerged from its first-round bye riding a seven-game win streak and hasn’t hosted a playoff game with fans at Lumen Field since January 2017. Darnold mentioned the atmosphere multiple times this week, noting how crucial it will be to “use cadence” on offense and let the 12s disrupt Purdy’s communication.
Shanahan deserves credit for keeping this team competitive despite a season ravaged by injuries. The Niners lost Nick Bosa to a torn ACL, Warner to the fractured ankle, and now Kittle to the Achilles. Brock Purdy is 4-0 at Lumen Field in his career. But playoff football at Lumen Field, against the conference’s best defense (ranked 3rd by PFSN at 88.4, B+), with a depleted roster? That’s a different challenge.
San Francisco will compete for the first half. Shanahan’s scheme consistently generates early success, and Purdy has the arm talent to make plays when protection holds. But there aren’t many teams in this league built to hang with Seattle for 60 minutes, and this banged-up Niners roster figures to wear down as the game progresses.
Prediction: Seahawks 27, 49ers 16
