Cowboys vs. Packers NFL Betting Promos: Odds, Prediction, How to Watch

Cowboys vs. Packers (8:20 p.m. ET, NBC/Peacock) kicks off Sunday Night Football live from Lambeau Field, and new bettors who stack tonight’s NFL betting promos can push their combined sign-up value well past $1,000, whether that shows up as bonus bets, a bet match, or a no-sweat first wager that pays regardless of the final score.

This is also one of the week’s biggest line moves. Dallas opened as a 1.5-point road favorite, but a lopsided Thursday night loss to a previously winless Buccaneers team flipped the number: Green Bay is now favored at home. That kind of volatility tends to push bettors to check multiple books rather than settle on the first offer they see.

Cowboys vs. Packers Odds for SNF Week 6

Green Bay has become the slight home favorite after Dallas’s rough Thursday-night showing. Here’s how the market prices it:

Key Storylines for Sunday Night

• Dallas arrives at 2-3 after a 24-16 loss to Tampa Bay last Thursday, a result that flipped this line in Green Bay’s favor.
• The Packers sit at 3-2 and have won back-to-back games, including a dominant showing against Chicago.
• Jordan Love and Dak Prescott headline an offensive matchup oddsmakers expect to produce points, with the total climbing from 50.5 to 53.5.
• Dallas is 4-1 to the Over this season, while Green Bay’s defense will be tested at home against a Cowboys offense that keeps pace even in losses.
• Mid-October at Lambeau Field typically means cooler temperatures, but conditions remain manageable for both passing attacks.

How to Watch Cowboys vs. Packers on SNF

• Location: Lambeau Field – Green Bay, Wisconsin

Cowboys vs. Packers Sunday Night Football Prediction

Green Bay’s defense has looked sharper the last two weeks, but Dallas enters with a legitimate edge: the Cowboys are 2-0 against the spread as underdogs this season, and ESPN’s Football Power Index still has them as the slight favorite to win outright despite the number flipping against them. Dak Prescott and an offense that’s 4-1 to the Over face a Packers team catching a wave of public money after reclaiming home-field favoritism following Dallas’s short-week stumble. That kind of lopsided public support often creates value on the other side, and it's worth weighing NFL public betting splits before locking in. With Dallas getting rest advantage on extra days off and a track record of hanging with anyone on the scoreboard, the points look like enough cushion.

9. BetRivers

BetRivers bonus code kicks in if your opener loses, and a win just pays standard odds. That setup suits bettors who genuinely like a side in this one rather than those hedging for guaranteed value. Terms vary more by state here, so check your app’s specific offer first.

10. Borgata

New Jersey-only, but worth a look for bettors in-state. The Borgata bonus code ACTION plus a $20 bet to get $100 in bonus bet credits instantly, no need to wait for the final score. Those credits expire in seven days, so plan to use them across the rest of the week’s slate.
