How the Fanatics Sportsbook Promo Code ACTION350 Works
The Fanatics Sportsbook promo code ACTION350 can return up to $350 in FanCash during the first seven days of an eligible account.
Users must opt into the promotion through the bet slip and place a qualifying $20+ cash wager at odds of -500 or longer. Fanatics can then award $50 in FanCash for that promotional day under the offer terms.
The Action Network promotion requires users to opt in each day, so the full $350 is not deposited at once. FanCash issued through this offer also expires 24 hours after it is awarded.
That makes the timing important. Rather than treating the $350 as one large bonus balance, users should plan around the daily FanCash credits and use each reward before it expires.
Lions vs. Bills Odds
Lions vs. Bills kicks off Thursday at 8:15 p.m. ET on Prime Video from the new Highmark Stadium in Orchard Park.
Buffalo has moved to around a 4.5-point favorite on Fanatics Sportsbook NFL odds entering Wednesday, while the total sits near 53.5.
| Market | Detroit Lions | Buffalo Bills |
|---|---|---|
| Spread | +4.5 (-110) | -4.5 (-110) |
| Moneyline | +170 | -200 |
| Total | Over 53.5 (-110) | Under 53.5 (-110) |
Detroit's offensive line is the main situation to monitor. Christian Mahogany, Blake Miller and Juice Scruggs have all dealt with injuries during the short week, while Cade Mays remains unavailable.
Buffalo enters Thursday with fewer major concerns, although its final injury designations are still worth checking before kickoff.
The matchup also carries an unusual home-field element. Thursday will be Buffalo's first regular season game at the new Highmark Stadium, giving the Bills a home opener against another 1-0 team.
Lions vs. Bills Prediction
Buffalo is my preferred side given the current lines on Fanatics Sportsbook.
- Lions vs. Bills prediction: Bills -4.5 (-110)
Detroit has enough offensive talent to make this competitive, but uncertainty along the offensive line creates a difficult matchup on the road. Protecting Jared Goff becomes especially important against a Buffalo front that should have opportunities to create pressure.
The Bills also get Josh Allen at home in the first regular season game at their new stadium. Buffalo does not need to dominate offensively to cover this number; a touchdown ahead and a win is enough.
