Underdog promo code LABSNEWS: Create a lineup with NFL Week 15 picks
The Underdog promo code LABSNEWS unlocks $100 in bonus entries for DFS picks on Sunday’s NFL slate. All you need to do is submit a $5 lineup after signing up with the Underdog Fantasy promo code LABSNEWS, and Underdog credits your account with $100 in bonus value—win or lose. As one of the top DFS sites available, Underdog features player projections from every matchup on the Week 15 schedule.
Updated on 12/21/25
To build your first Underdog entry, select between two and eight players and choose whether each will finish Higher or Lower than their posted statistical projection. Adding more picks increases your payout multiplier and boosts your upside.
Below are three of my favorite NFL picks for Sunday. Sign up with the Underdog promo code LABSNEWS, then use these selections as a starting point or create your own lineup from scratch.
- Baker Mayfield to get “Higher” than 230.5 passing yards
- Jaxson Dart to get “Higher” than 197.5 passing yards
- Chris Godtin to get “Lower” than 33.5 receiving yards
Once you’ve finalized your player picks, decide how you want to submit your NFL entry. A Standard Entry offers the highest payout multiplier, but it comes with no margin for error—every pick must hit for the entry to cash. A Flex Entry provides added protection, allowing you to earn a payout even if one selection falls short, though the multiplier is reduced due to the lower risk.
To illustrate, a three-pick Standard Entry pays 6x your stake if all three projections hit. Submit those same picks as a Flex Entry, and the return drops to 3x or 1x, depending on how many of your selections clear their projections.
