Conner on IR and a QB Room in Flux: Arizona’s Rebuilt Cardinals Face an Unforgiving Start

The Arizona Cardinals entered the September cutdown with a clear identity crisis, and the last 48 hours did nothing to resolve it. After trimming to 53 on Sunday, the team placed veteran running back James Conner on injured reserve — a move that leaves first-year head coach Mike LaFleur’s offense without its most trusted playmaker as the 2026 opener at the Los Angeles Chargers rapidly approaches.

Conner’s IR stint was largely expected after a preseason riddled with ailments — the back logged everything from ankle to ribs to shoulder issues across the injury report. The designation doesn’t end his season, but it leaves Arizona to lean on a running back room that is suddenly both young and unproven. Trey Benson is also on IR, meaning the Cardinals could open the year with Jeremiyah Love, Evan Hull, and free-agent addition Tyler Allgeier splitting the workload. Local beat coverage has already pegged Love as a "big winner" of the roster cuts, but expecting a first-year back to replace Conner’s bell-cow production against a Chargers front is a tall order.

The front office, holding the third spot in the waiver order, is reportedly eyeing defensive-line help. That’s a sensible priority for a unit that surrendered 488 points during last year’s 3-14 collapse, but it leaves the offense skating on thin ice at the skill positions.

Then there’s the quarterback situation, which remains the defining mystery of the LaFleur era. Kyler Murray was released in the spring and landed in Minnesota, officially closing a seven-year chapter that produced just one playoff appearance. In his place, the Cardinals have assembled what is effectively a veteran competition: Jacoby Brissett and Gardner Minshew headline the room, with Carson Beck — who showed flashes in the Hall of Fame Game — waiting in the wings. Depth charts currently slot Brissett first, and his steadiness likely gives Arizona its best chance at stability. But the presence of both Minshew and Beck suggests LaFleur hasn’t fully committed, and the preseason finale didn’t settle anything. That game, fittingly, was a 42-38 loss to Matt LaFleur’s Green Bay Packers — the first-ever "LaFleur Bowl" — with the teams trading touchdowns in a shootout that revealed how far Arizona’s defense still has to go.

The schedule will make patience difficult. Multiple outlets have ranked the Cardinals’ 2026 slate as the hardest in the league, beginning with a road trip to face the Chargers, followed immediately by divisional contests against the Seahawks and 49ers. Sportsbooks aren't expecting a turnaround — Arizona sits at 500-to-1 to win the Super Bowl, a number that reflects the market's view of a roster still in the early stages of reconstruction.

For LaFleur, though, the evaluation metrics are different. The Cardinals aren’t being judged on wins in September; they’re being judged on whether a clear quarterback emerges, whether Love and the young backs can keep the run game respectable, and whether the defensive additions can generate any pressure. Those are the improvements that will define the rebuild.

The Conner injury forces the issue sooner than Arizona would like. But it also gives the new staff an immediate, unambiguous test: can this offense function without its most reliable weapon, and can anyone in the QB room actually carry it when it matters? The answer over the next month will tell us far more about LaFleur’s Cardinals than the win-loss column ever could.
