The NFL preseason continues on Friday night, and first-time bettors at BetMGM can use the BetMGM bonus code POSTBET for up to $1,500 back in bonus bets if your first bet doesn’t win.
The Dolphins and Commanders will clash on Friday night as we get a look at a couple of teams in two very different chapters of their journey.
BetMGM bonus code POSTBET for Dolphins vs. Commanders
BetMGM bonus code POSTBET allows customers to get their first bet back in bonus bets if their first bet doesn’t win, up to $1,500.
For newcomers, that means you can make a wager as low as $10 or as high as $1,500 for your first wager and if your bet loses, you’ll receive bonus bets equal to the amount you wagered. The catch is those bonus bets are non-withdrawable.
This offer is available in the following states: Arizona, Colorado, Iowa, Illinois, Indiana, Louisiana, Kansas, Kentucky, Massachusetts, Maryland, North Carolina, Ohio, Tennessee, Virginia, Washington DC, and Wyoming.

What our Post expert thinks about Dolphins vs. Commanders
It’s a new era for the Fish as Jeff Hafley takes over for Mike McDaniel, while Malik Willis is slotted to be the No. 1 quarterback in Miami for the upcoming campaign.
The Commanders are looking to bounce back after a disappointing 2025 campaign that saw them miss the postseason.
