Seahawks vs. 49ers Player Props for NFL Week 18 Tonight | Best Prop Bets & TD Picks
Last Updated: January 3, 2026 7:48 PM EST • 3 minute read X Social Google News Link
My best Seahawks vs. 49ers player props focus on Sam Darnold, Jaxon Smith-Njigba, and Jauan Jennings. The Seahawks are a 1.5-point betting favorite for tonight's 8 p.m. ET (ABC/ESPN) kickoff from Levi’s Stadium in Santa Clara, Calif.
With the NFC’s No. 1 seed on the line, I highlight why I expect Darnold and Smith-Njigba to take advantage of a pass defense that ranks in the bottom 10 in the league. Additionally, my NFL Week 18 predictions discuss what Jennings will need to do to score in his sixth consecutive game.

Jaxon Smith-Njigba Over 7.5 receptions (+114) ⭐⭐⭐⭐
When these teams met back in Week 1, Smith-Njigba caught nine passes for 124 yards. He hasn’t let up since, catching at least eight passes in 10 of his 16 games. He’s been targeted at least 12 times in back-to-back games.
The 49ers rank 24th in receiving yards allowed, giving up an average of 244.5 per game. They’ve also allowed 378 receptions, third-most in the NFL.
FanDuel's plus-money price is the top option across our best sports betting sites.

Sam Darnold Over 237.5 passing yards (-115) ⭐⭐⭐⭐
Darnold threw for just 147 yards last week, but he’s thrown for at least 249 in three of his last four contests and has 10 performances with at least 240 yards this season.
San Francisco has been vulnerable through the air, surrendering 235.6 passing yards per game - 25th in the NFL. That lines up neatly with Sam Darnold’s efficiency this season, as he’s completing 67.2% of his throws, nearly identical to the 67.7% completion rate the 49ers are allowing to opposing quarterbacks.
Jauan Jennings to score a touchdown (+180) ⭐⭐⭐
After catching a 38-yard touchdown last week, Jennings has now scored in five consecutive games and seven of his last eight overall. While he had only one other catch last week, the performance highlighted Jennings’ knack for finding the end zone, even with limited chances.
The Seahawks have allowed just nine rushing touchdowns, second-fewest in the league, so I expect any scoring the 49ers do to come through the air. Jennings has nine receiving touchdowns to lead all 49ers.
If you think he'll make it six straight, head over to DraftKings.
