Week 5’s late window is built around one NFC West matchup, and the Underdog promo code LABSNEWS gives eligible new users $100 in bonus funds after $5 in qualifying entries. The unbeaten 49ers visit the Seahawks at Lumen Field on Sunday at 4:25 p.m. ET on FOX.
San Francisco is 4-0 with one of the most efficient passing attacks in the NFL , while Seattle is 3-1 behind the NFL’s stingiest pass defense and an offense heavily concentrated around Jaxon Smith-Njigba. That gives us several NFL DFS pick options from 49ers vs. Seahawks.

How the Underdog Promo Code LABSNEWS Works
Sign up with LABSNEWS, play $5 in qualifying entries and Underdog adds $100 in bonus cash after the offer requirements are met. Check the promotion terms in the app for how the bonus is issued and when it can be used.
Underdog is a pick’em platform. You choose whether a player finishes Higher or Lower than the projection listed in the app, then combine eligible selections into one entry.
On a single-game slate, the best approach is to build around a consistent view of how the matchup plays out. Seattle’s secondary can limit San Francisco’s downfield passing volume without eliminating production from George Kittle or Christian McCaffrey, while Seattle’s concentrated receiving tree keeps Smith-Njigba involved regardless of game script.
49ers vs. Seahawks Picks
| Player | Stat | Pick |
|---|---|---|
| Jaxon Smith-Njigba (SEA) | Receiving yards | Higher |
| George Kittle (SF) | Receiving yards | Higher |
| Christian McCaffrey (SF) | Rushing + receiving yards | Higher |
| Brock Purdy (SF) | Passing yards | Lower |
| Sam Darnold (SEA) | Passing yards | Lower |
The picks all follow the same game script. Seattle’s offense is heavily concentrated around Smith-Njigba, while San Francisco’s injuries should keep Kittle and McCaffrey central to the offense. At the same time, Seattle’s elite pass defense makes Purdy’s passing-yardage Lower appealing, and Darnold has averaged fewer than 190 passing yards per start. That gives us three star-player Highers without needing either quarterback to post a huge yardage total.

Conclusion
Smith-Njigba remains the clearest Seattle Higher pick because so much of the passing game runs through him. Kittle and McCaffrey give San Francisco ways to produce without requiring a huge passing-yardage performance from Purdy.
That same script supports the quarterback Lowers. Seattle’s pass defense can keep Purdy’s volume under control, while Darnold has not needed a big yardage total for Smith-Njigba to produce.
