Underdog Promo Provides $1K Deposit Match for Bills-Lions TNF

Underdog is offering new users a 50% deposit match up to $1,000 with promo code FOXSORTS, plus access to its Keep Your Millions promotion. The deal is tied to Thursday's Bills-Lions game, where both offenses are expected to be explosive. Users must sign up and deposit to claim the bonus.
The promotional offer arrives ahead of a Week 2 matchup between two high-scoring offenses. Buffalo's opener featured 470 total yards and 41 points, with Josh Allen accounting for four touchdowns through the air and on the ground. Detroit countered with 30 points of its own, powered by Jared Goff's two touchdown passes and a pair of scores from Jahmyr Gibbs.
Both defenses showed vulnerability in Week 1, with Buffalo surrendering 31 points and Detroit allowing 30 despite generating five sacks and three takeaways. The game airs Thursday at 8:15 p.m. ET on Amazon Prime Video from Highmark Stadium. Underdog's Keep Your Millions promotion grants new users a virtual $1 million bankroll to manage throughout the NFL season.
This promotion could draw new bettors into the sports wagering ecosystem during a marquee Thursday night matchup between two offensive powerhouses. The deposit match structure may encourage larger initial deposits than users would otherwise make, potentially increasing gambling exposure for newcomers. The Keep Your Millions format, which simulates managing a large virtual bankroll, could normalize high-stakes decision-making patterns. As sports betting continues expanding across states, such aggressive acquisition offers may shape how casual fans engage with NFL games, shifting focus from pure fandom toward wagering considerations.
