Use Underdog Promo Code TOPACTION to Place Vikings vs. Cowboys Prediction
I'm not the only one who highly regards the Underdog promo code TOPACTION and $75 new user promo that's up for grabs. Action Network sportsbook expert Nick Sterling believes Underdog is worth signing up for, largely due to the fact that $75 in bonus entries is too good a deal to pass up.
"I'm always looking to maximize winnings, and using Underdog's $75 in bonus entries is a great way to win big at a low cost, while having fun."
With that said, register now using the Underdog promo code TOPACTION to get in on the action today. Tonight's game between the Vikings and Cowboys is a star-studded affair, which makes it all the more fun to make picks on. My SNF pick 'em entry is as follows:
| Player | Team | Pick |
|---|---|---|
| Brandon Aubrey | Dallas Cowboys | Higher Than 1.5 Field Goals Made |
| Javonte Williams | Dallas Cowboys | Lower Than 72.5 Rushing Yards |
| Justin Jefferson | Minnesota Vikings | Lower Than 61/5 Receiving Yards |
Before you submit a player pick 'em entry, decide between a Max Payout or Flex Payout on your prediction. Every pick must hit to win money off a Max Payout, but you win more money that way than if you pick Flex. The benefit to a Flex Payout is you still win some money if one of your picks is incorrect.
