Underdog bonus code: Get $50 in Bonus Entries for Week 3 in the NFL

Underdog is offering new customers $50 in bonus entries for NFL Week 3 when they sign up with a promotional code and place an initial entry of at least $5. The promotion comes after a series of quarterback injuries in Week 2, including issues affecting Caleb Williams, Jayden Daniels, and Jaxson Dart, which opens opportunities for backup signal-callers across daily fantasy contests.

Week 3 features notable matchups across the league, including the NFL's first game in Rio De Janeiro featuring the Dallas Cowboys and Baltimore Ravens. Elsewhere, the Cincinnati Bengals travel to face the Pittsburgh Steelers, while Lamar Jackson and Detroit Lions wide receiver Amon-Ra St. Brown are highlighted as prominent fantasy options.
