I signed up with Underdog promo code TOPACTION ahead of Steelers-Bengals yesterday and utilized the 50% first deposit match that came with being a new player. Now, I encourage you to register and get half of your first deposit matched, up to $1,000 in bonus funds.
Monday Night Football provides a fun window to target your Underdog bonus funds on. Philadelphia visits Chicago tonight at 8:15 p.m. ET from Soldier Field, and the injury to Caleb Williams is the biggest storyline ahead of Eagles vs. Bears on ESPN.

Terms to Note Before You Deposit
Every deposit match carries fine print, and these pieces of information caught my eye when I signed up with Underdog promo code TOPACTION from Action Network:
- Underdog credits bonus funds within 72 hours of the first deposit
- Bonus funds apply to fantasy entries only, not straight picks on Underdog Predict
- Entries need a payout multiplier of 2x or higher to accept bonus funds
- Bonus funds expire 14 days after they hit your account
- Playthrough covers the deposit plus the bonus before any withdrawal clears
- Age minimums sit at 18 in most states, 19 in Alabama and Nebraska, and 21 in Arizona, Massachusetts, and Virginia
Underdog DFS Basics for New Players
Higher or Lower contests drive the Underdog lobby, and they read like player projections rather than traditional NFL odds. You combine two to five picks, choose Higher or Lower on each projection, and watch the multiplier climb with every leg you add.
Two leg entries pay less but survive far more often, which is exactly why I start new accounts there. Best Ball drafts and Rivals matchups fill out the rest of the app.

Eagles vs. Bears NFL DFS Picks on Underdog
Case Keenum gets the start tonight with Caleb Williams out due to hamstring injury and Tyson Bagent spending the week in concussion protocol. Keenum makes his first start since the 2023 season, and that is at the front of my mind when making my Eagles vs. Bears predictions on Underdog this evening:
D'Andre Swift Receiving Yards: Higher
Swift drew six targets in Week 2 after seeing just one in the opener. I expect Keenum to dump the ball off to his checkdown early and often while finding his footing. The mark for Swift to beat is 10.5, a line he has cleared in 14 of 20 games under Ben Johnson.
DeVonta Smith Receiving Yards: Higher
Smith owns this offense now that Philadelphia traded A.J. Brown, and he posted a 39% target share with a 63% air yards share last week en route to 117 yards and a score. Chicago ranks 20th in EPA per pass despite drawing two soft quarterback matchups.
Kyle Monangai Rushing Yards: Higher
The Eagles rank 27th in EPA per rush and surrender the fifth most yards after contact per attempt. Monangai led the entire league in rush yards over expected per attempt in Week 1, and a home team protecting a low total leans hard on the ground.
