Los Angeles hosts the game at SoFi Stadium in Inglewood, giving the Rams a true home-field setting against a Bills team that travels across the country, though with an extra day of rest after last playing on Oct. 4.
Buffalo's offense has cooled in recent weeks, with Allen throwing one touchdown pass against three interceptions over his last two games, but he still leads the NFL with seven rushing touchdowns, and James Cook paces the run game.
Los Angeles counters with Matthew Stafford distributing to Puka Nacua, and safety Quentin Lake is the only Rams player with a game-status designation, listed as questionable. Aaron Donald returns from a back injury that kept him limited in practice, giving the Rams front seven a jolt after missing him last week, while cornerback Jaylen Watson works back from a shoulder injury suffered earlier in the season.
Buffalo's own injury report has receiver Josh Palmer and defensive tackle Ed Oliver ruled out, with DJ Moore questionable after missing two practices with a shoulder injury, along with cornerback Dee Alford and defensive lineman Landon Jackson. Keon Coleman is cleared after a full week of practice, and he had six catches for 116 yards and a touchdown against New England after Moore left that game.
How Does the Kalshi Promo Code Compare to Novig and ProphetX Tonight?
New traders scanning every prediction market promo this week find a crowded field, and the Kalshi promo code stands out on pure bonus value. Novig’s current welcome offer pays $25 in trade credits on a $10 deposit, and ProphetX’s standard entry tier pays $20 on a $10 trade, with its richer $75 tier splitting into three separate installments over 45 days instead of landing in one payment.
| Platform | Entry Requirement | Bonus | Payout Timing |
| Kalshi (ACTION55) | Trade $25 | $55 | One payment after the trade settles |
| Novig | Deposit $10 | $50 | One payment after deposit |
| ProphetX | Trade $50 | $75 | Top tier splits into 3 installments over 45 days |
The Kalshi sign up bonus ACTION55 delivers the largest single bonus payment of the three tonight, and it clears as one lump sum rather than a drawn-out installment schedule.
Here's how the Kalshi promo code compares with two other prediction market welcome offers.
