New players who enter the Underdog Promo Code TOPACTION during sign-up can unlock $100 ahead of the Falcons vs. Saints Monday Night Football matchup.
The Atlanta Falcons host the New Orleans Saints at 8:15 p.m. ET on ESPN, and the Falcons vs. Saints matchup hands new DFS players a stacked player prop board to build a first lineup around. Fans who scan the NFL schedule or check NFL odds ahead of kickoff walk into this entry with a clearer read on pace, injuries, and which skill players draw the heaviest target share.
Using the Underdog promo code TOPACTION stays simple: open an account, drop a $5 entry on the board, and the site credits a $100 bonus once that first lineup settles with Underdog.

Why Choose the Underdog promo code for Falcons vs. Saints Tonight?
Underdog separates itself from a standard bonus code site because the entire platform runs on skill-based pick'em contests, and that format gives first-time players more control over the outcome than a single locked parlay leg. The Underdog Bonus Code unlocks a few categories worth knowing before tonight's opening kick:
- Player prop pick'em contests that let a user select over or under on rushing yards, receptions, or passing touchdowns for any starter in the Falcons vs. Saints lineup.
- Lower entry minimums than most season-long fantasy formats, so a $5 ticket carries the same bonus eligibility as a $25 one.
- Multiple active sports behind NFL, including an everyday DFS slate that keeps the welcome offer relevant year-round, a resource worth bookmarking from the best DFS promos this NFL season roundup
- Same-day payout processing once a lineup locks and the contest grades
New players who track NFL futures markets alongside tonight's game often carry that same research habit into their first player prop picks.
How Do I Claim the Underdog Bonus Code?
- Visit the sign-up page and enter the Underdog Promo Code TOPACTION during registration
- Confirm identity and state eligibility
- Deposit at least $5 into the account
- Place a qualifying $5 entry on any available contest
- Receive a $100 bonus credit once that entry settles
What Else Can You Use Your Underdog Promo Code On?
New users who redeem the Underdog Promo Code TOPACTION this week don't need to rush a lineup before Monday's kickoff, since the $100 bonus credit carries a standard redemption window that stretches well past tonight's game. With 7 days to use the bonus funds across any active contest, you can comfortably cover Tampa Bay's trip to Dallas for Thursday Night Football in Week 5 on October 8.
That expiry structure works in a new user's favor heading into Week 5:
- Day 1 (Monday, Oct. 5): Bonus credit posts after the Falcons vs. Saints lineup grades
- Days 2-3 (Tuesday-Wednesday): Full access to build and enter lineups using bonus funds
- Day 4 (Thursday, Oct. 8): Buccaneers-Cowboys Thursday Night Football kicks off, still well within the active bonus window
- Days 5-7 (Friday-Sunday): Remaining runway to use any leftover bonus funds on Week 5's Sunday slate before the window closes
A new player who holds off until Thursday still has three full days of runway left after that TNF matchup, rather than feeling pressure to spend the bonus the same night it lands.
