The Bills entered the game with a 4-1 record, having started the season with a dominant 2-0 mark before a narrow loss to the New England Patriots. Their offense, led by Allen, had shown explosive potential, but also a tendency for turnovers, as seen in a 24-16 win over the Chargers where they committed five. The Rams, on the other hand, had a rocky start, losing two of their first three games, but they rebounded with a dramatic 24-20 comeback victory over the Philadelphia Eagles on October 4, 2026. That win, powered by two late touchdowns from Kyren Williams, gave them momentum and a 2-2 record heading into the Monday night contest.
The game itself was a back-and-forth affair, with six consecutive lead changes. The Rams tied the game at 34-34 with a one-yard touchdown run by Kyren Williams with only four seconds left in regulation, forcing overtime. In the extra period, the Bills drove into Rams territory but lost a fumble, recovered by Aaron Donald. The Rams then moved into field goal range, but their kicker, Harrison Mevis, had his attempt blocked by Greg Rousseau, setting up the Bills' game-winning drive.
