Overview
- Kickoff is 8 p.m. ET at Levi's Stadium in Santa Clara, with sportsbooks listing Seattle around -1.5 and a total near 48.
- The winner clinches the division, the conference’s top seed, a first-round bye, and home-field advantage throughout the NFC playoffs.
- Both teams ride six-game winning streaks, with the Seahawks at 13-3 and the 49ers at 12-4 entering Week 18.
- The matchup pits Seattle’s elite defense and pressure metrics against a revitalized San Francisco attack led by Brock Purdy and Christian McCaffrey.
- San Francisco’s pass rush has lagged after season-ending ACLs to Nick Bosa and Mykel Williams, and Kyle Shanahan says Trent Williams will play only with medical clearance.
