How to Use Underdog Fantasy Promo Code TOPACTION for NFL Thanksgiving Games
The Underdog Fantasy promo code TOPACTION is one of the best ways to get started on daily fantasy sports (DFS) for Thanksgiving games. Here’s what expert Chris Ilenstine has to say about claiming this welcome offer:
“If you’re serious about playing DFS this Thanksgiving, this is the promo to grab. The Underdog promo code TOPACTION gives you extra value right away — it’s like starting your lineup with a lead before kickoff."
To build your Underdog lineup, simply select "Higher" or "Lower" on a player projection. The more picks you add, the bigger your potential payout. If your lineup includes three or more picks, you must choose between:
- Standard entry – Largest payout, but only if all picks win.
- Flex lineup – Smaller payout for a perfect entry, but you can still profit or get your stake back if one pick loses.
Below, you'll find my Underdog lineup example for NFL Thanksgiving games, including Chiefs vs. Cowboys at 4:30 p.m. ET on CBS and Bengals vs. Ravens at 8:20 p.m. ET on NBC.
| Player | Team | Pick |
|---|---|---|
| George Pickens | Dallas Cowboys | Higher Than 75.5 Receiving Yards |
| Lamar Jackson | Baltimore Ravens | Lower Than 230.5 Passing Yards |
| Noah Fant | Cincinnati Bengals | Higher Than 15.5 Receiving Yards |

George Pickens’ first season with the Cowboys has been nothing short of spectacular, as he ranks second in the NFL with 1,054 receiving yards. Pickens has been on fire lately, recording 78 or more receiving yards in six consecutive games, and I don’t see that streak ending in today’s matchup against the Chiefs.
On the other side, Lamar Jackson has struggled since returning from a hamstring injury. He hasn’t surpassed 205 passing yards in his last four games, yet the Ravens keep finding ways to win. While the Bengals have one of the league’s weaker defenses, it’s tough to back Jackson given his recent numbers.
Sticking with the Bengals vs. Ravens game, we should expect increased production from Noah Fant. Prior to last week, Fant had five straight games with 27 receiving yards. With Joe Burrow back and Tee Higgins sidelined, Fant should have no trouble clearing 16 receiving yards on Thanksgiving.
