Seattle Seahawks quarterback Sam Darnold rips a pass over the middle to wide receiver Jaxon Smith-Njigba who makes an unbelievable adjustment in mid air to haul in the 19-yard catch in Week 18 against the San Francisco 49ers.

Sam Darnold completed 20 of 26 passes for 198 yards in the win. While efficient through the air, Seattle leaned heavily on its ground game. Kenneth Walker rushed for 97 yards on 16 carries, while Zach Charbonnet added 74 yards and a touchdown on 17 attempts. On the other side, Purdy finished 19 of 27 for 127 yards with one interception.

Saturday night’s game between the San Francisco 49ers and the Seattle Seahawks will be full of overreactions. Whichever teams win will be prematurely crowned, while the loser will be treated like a team that doesn’t deserve to make the postseason. Here’s how we believe tonight’s game will go.

The Seahawks Dominated On Defense And With Their Running Game To Clinch The NFC West With A 13-3 Win Over The 49ers

In one of the most consequential games of the 2025 NFL season, the San Francisco 49ers host the Seattle Seahawks on Saturday night.

Saturday night could be an NFC Championship preview. For now, we’ll call Saturday night Week 18’s prime-time matchup between the 49ers and Seahawks the NFC West championship game. San Francisco comes in as the 2.5-point underdog in their home matchup against the Seahawks.

The Seattle Seahawks will be without one of the team’s receivers for the foreseeable future. Seattle announced the news on December 30, 2025, just days before the team takes on the San Francisco 49ers with both the NFC West title and No. 1 seed on the line.

Amid this win over the 49ers, the Seahawks' defense tied NFL history with Kyle Shanahan-led offenses. Touted as one of the game's best playcallers, this history-making game from Seattle shows just how great this defense is.
