Use Underdog Fantasy Promo Code TOPACTION for NFL Week 18 Lineup
Sign up with the Underdog Fantasy promo code TOPACTION and make your first deposit to unlock bonus funds. Use these bonus funds to create a lineup on Sunday, with plenty of options available on the NFL pick'em board.
Select "Higher" or "Lower" on a player projection to build your lineup. You can include between two and six picks in your lineup. Depending on its size, you may need to choose between a Standard lineup or a Flex lineup for different payout opportunities.
For example, with a three-pick lineup, a Standard lineup offers a 6x payout if all your picks win. A Flex lineup provides a 3x payout for a perfect entry, while winning two out of three picks still returns a 1x payout.
- Malik Nabers (New York Giants) Higher Than 6.5 Receptions
- Jaxon Smith-Njigba (Seattle Seahawks) Higher Than 66.5 Receiving Yards
- Tyler Huntley (Miami Dolphins) Lower Than 215.5 Pass + Rush Yards
Malik Nabers has had a stellar rookie season and is just two receptions away from breaking the rookie record for most catches in a season. He's recorded 7+ receptions in four of his last five games and looks set for another standout performance against an Eagles squad likely resting its top players.
Jaxon Smith-Njigba has quietly emerged as one of the NFL’s top wide receivers, ranking in the top 10 for both receptions and receiving yards. After a rain-affected struggle last week, he’ll look to rebound against a Rams defense expected to rest key starters. Before last week, Smith-Njigba had eight consecutive games with 66 or more receiving yards.
My final pick targets Tyler Huntley falling short of his pass + rush yards projection. While Huntley posted solid numbers against the Browns last week, he'll face a far stiffer challenge against the Jets’ defense, which ranks top five in passing yards allowed.
