Packers rally late to beat Cardinals 42-38 in a wild Lambeau preseason finish

The preseason finale at Lambeau Field delivered exactly what Packers coach Matt LaFleur promised would be an unusually entertaining game. Green Bay erased a late deficit and finished with a 42-38 win over the Arizona Cardinals on Friday night, completing a fourth-quarter comeback that shifted the momentum in a hurry.

The final score alone tells part of the story, but it also sets the tone for what preseason football can look like when both teams lean into evaluation. With both sides playing with a sense of urgency to generate live-game results, the game opened up in the final minutes and allowed swings in possession and scoring that made the end of the night feel different from typical “work through the reps” preseason contests.

For the Packers, a comeback win matters beyond the two points in the standings, because it reflects something teams are always trying to build in training camp and the preseason: the ability to stay composed when the plan changes. Preseason rosters are in constant flux, and late-game sequences often become a test of execution, decision-making, and whether younger players can operate effectively under pressure.

For the Cardinals, a game like this can be useful even in defeat. Arizona still faced the reality of the Packers adjusting late, and that is the kind of experience that can help teams calibrate how they protect leads, manage pace, and respond when an opponent finds rhythm in the second half. Conceding late can expose schematic issues, but it can also highlight the need to win critical moments when defenses are asked to cover longer stretches of time.

LaFleur’s description of the game as “the most entertaining preseason game you’ve ever seen in your life” framed the night as a showcase of the volatility that preseason carries. That volatility is, in many ways, the point. Coaches are not only grading fundamentals and depth, they are looking for report from players who can make plays when the script stops cooperating.

The Packers’ 42-38 result also underscores how quickly preseason football can turn into a track meet. Even with normal roster management, games at this stage can produce large scoring totals when teams are testing matchups and rotating personnel frequently. The takeaway for both organizations is to translate what they saw late into clearer priorities for the remaining weeks before the regular season begins.

What to watch next is how Green Bay uses the late-game energy from this win as it continues its roster setting process. Preseason finales often function as the last meaningful checkpoint, and the clearest value is in which players consistently perform in the moments that matter most. For Arizona, the focus will be on closing out games and tightening late-game execution, so the kind of finish that produced a Packers comeback becomes less likely as the calendar moves toward the regular season.
