Cardinals vs Raiders Preseason Prediction: Beck-Mendoza Rematch Headlines Week 1 Opener

The preseason slate rolls on Thursday night when the Arizona Cardinals travel to Allegiant Stadium to face the Las Vegas Raiders in Week 1 of the 2026 NFL preseason, kicking off at 8:00 p.m. ET. This is actually the Cardinals’ second exhibition outing of the summer, since Arizona was tapped for the Hall of Fame Game against the Carolina Panthers last week, giving them an extra tune-up before the regular season. The Raiders, on the other hand, are opening their preseason slate fresh, and both coaching staffs have signaled this one will look more like a real game than most preseason openers.

Cardinals head coach Mike LaFleur confirmed his starters will see the field, including quarterback Jacoby Brissett, who returns from a lengthy contract holdout that kept him out of full practice reps until roughly two weeks ago. LaFleur has been clear that playing time will be limited for his top players — “one drive, max of two” for the “main guys” — but the fact that Brissett is playing at all is notable given his late start to camp. Raiders coach Klint Kubiak has been similarly committed to fielding his starters, though he left the exact snap count more ambiguous, noting only that rookie quarterback Fernando Mendoza will “get plenty of reps” once the backups take over.

What the Vegas Books Are Really Saying With This Line

Oddsmakers have the Raiders as short home favorites, with the spread hovering between -0.5 and -2.5 in Las Vegas’ favor depending on the book, and the moneyline sitting around -130 to -135 for the Raiders against +110 to +114 for Arizona. The total is set in the 39.5 to 42 range, which is fairly standard preseason territory — expect scoring to slow considerably once the backups and camp bodies take over in the second half. It’s worth remembering that preseason lines are notoriously thin and soft; sportsbooks aren’t devoting the same modeling resources to Week 1 exhibition football that they do to the regular season, and liquidity is light. A half-point or full point of line movement can happen on a single beat writer’s report about who’s active. Books are essentially pricing in a game where each team’s stars log a series or two before handing things to a rotating cast of camp hopefuls, which makes the number more about roster-management news than actual matchup analysis.

The Quarterback Rematch Everyone’s Circling

The headline subplot here is a rematch of last season’s College Football Playoff national championship game. Carson Beck, Arizona’s third-round rookie who led Miami into that title game, will likely see the field for the Cardinals once Brissett and Gardner Minshew cycle out. Beck was the story of the Hall of Fame Game, completing 15 of 19 passes for 188 yards and a touchdown for a sparkling 125.4 passer rating in his professional debut. On the other side, Fernando Mendoza — the No. 1 overall pick out of Indiana who beat Beck’s Miami squad in that championship game — is working through his first NFL camp behind veteran starter Kirk Cousins. Mendoza has drawn praise from Raiders coaches and reporters for his command of the second-team offense, throwing just one incompletion in one notable practice session, though he’s also had a couple of uneven days mixed in, which is normal for a rookie absorbing an NFL playbook.

Beyond the quarterbacks, there are real roster battles worth tracking. Arizona’s No. 3 overall pick, running back Jeremiyah Love, is expected to make his NFL debut in this game after sitting out the Hall of Fame Game. Love enters a crowded backfield with James Conner and Tyler Allgeier, and offensive coordinator Nathaniel Hackett’s recent comment that Love “looks like a rookie” in practice has added a bit of an edge to how closely his workload gets watched Thursday night. On the Raiders’ side, rookie fifth-round cornerback Hezekiah Masses has been one of the more pleasant surprises of training camp, working with the first-team defense and even picking off Cousins in a recent practice. Masses is squarely in the mix for the CB2 job opposite Eric Stokes, and a strong preseason debut would only strengthen his case. Raiders star edge rusher Maxx Crosby, back healthy after an offseason of rehab, is also worth watching if he sees any early snaps, given how much energy he’s brought back to camp.

Injury notes matter here too. Arizona is dealing with absences at running back (Trey Benson) and along the defensive front, where edge rusher Josh Sweat has yet to appear in practice through three weeks of camp, though both LaFleur and general manager Monti Ossenfort have expressed confidence he’ll be ready for Week 1 of the regular season. None of that should affect Thursday’s game plan much, since neither Sweat nor Benson is in line for significant preseason snaps regardless.

Prediction and Best Bet

This projects as a game that starts competitive and gets loose late, which is the nature of preseason football once the top-two units clear the field. Brissett and the Cardinals’ starters should move the ball reasonably well behind LaFleur’s scheme in a short sample, while Cousins gets a clean look against a Raiders defense still installing its new identity. The bigger separator comes when Beck and Mendoza take over — Beck has already shown poise in a live setting, and that experience edge could show up again against a Raiders defense that will be rotating plenty of camp bodies by the second half.

• Prediction: Raiders 24, Cardinals 20
• Best Bet: Raiders on the moneyline

The short line and home value make Las Vegas the more logical side here, especially with Mendoza expected to get extended run and a defense that’s flashed some early camp intrigue at cornerback and up front. Given how thin preseason markets are, taking the home team at a manageable moneyline price is a cleaner way to attack this number than guessing which coach pulls starters after exactly one series.
