Cardinals turn to rookie Carson Beck for NFL debut as QB injuries pile up in Arizona

Carson Beck wasn't supposed to be starting NFL games in 2026. But after Jacoby Brissett was benched and traded to Baltimore following Week 8, and Gardner Minshew suffered an elbow injury against Seattle last week that could require season-ending surgery, the Arizona Cardinals' third-round rookie is now their quarterback — starting Sunday against the Los Angeles Rams.

The announcement, made Wednesday by head coach Mike LaFleur, confirmed what the Cardinals' depth chart had made inevitable. Beck — a third-round pick out of Miami who had been the emergency third-stringer early in the season — moves into a starting role with no one behind him to apply pressure. According to Sporting News, this is his job for the rest of the season.

The offense Beck inherits is significantly depleted. Wide receivers Michael Wilson, Kendrick Bourne, Jalen Brooks, and Marvin Harrison Jr. — who was traded weeks ago — are all unavailable. That leaves Beck throwing primarily to rookie Reggie Virgil, Simi Fehoko, Devin Duvernay, and Harrison Wallace III, according to Sporting News. Tight end Trey McBride remains healthy and figures to be Beck's most reliable target. Running back Tyler Allgeier is available, and Bam Knight may return from a concussion. Center Hjalte Froholdt's status is also uncertain heading into the week, according to Yahoo Sports.

Virgil, the rookie receiver out of Texas Tech, is expected to serve as Beck's top option — a pairing that connected in the preseason but now must produce immediately against a Rams defense that includes Myles Garrett and Aaron Donald.

The Rams enter Week 10 at 5-4, in what Sporting News describes as desperation mode to keep their playoff hopes alive — meaning Arizona's debut starter faces a motivated opponent with postseason stakes.

Beck's college résumé offered reasons for optimism and reasons for caution. The former Georgia and Miami quarterback started 43 games, processed quickly, protected the football, and posted a 38.6% first-down rate that ranked in the 95th percentile among draft-eligible quarterbacks from 2015–26, according to CBS Sports. But he faced pressure on just 19.1% of college dropbacks — the lowest rate among quarterbacks going back more than a decade — and more than 32% of his throws were screens. He was rarely asked to improvise when plays broke down.

There are structural reasons to think the Cardinals' offense could suit him. Arizona has attempted 58.8% of its passes within five yards of the line of scrimmage, and the offensive line has allowed pressure on 31.1% of dropbacks — the fifth-lowest rate in the NFL, according to TruMedia data cited by CBS Sports. Beck's reported strengths — accuracy, anticipation, playing on schedule — align with what the scheme asks.

But the real stakes extend well beyond Sunday. With eight games remaining, Beck has a window to determine whether Arizona uses what will almost certainly be a top-10 draft pick on another quarterback next spring. CBS Sports points to Tyler Shough as the recent model: selected 40th overall by New Orleans in 2025, Shough took over in Week 9, went 5-4, completed nearly 68% of his passes, and gave the Saints enough confidence to pass on drafting a quarterback in 2026 — instead using the eighth pick on wide receiver Jordyn Tyson.

The historical record for late-starting rookie quarterbacks drafted in the third round or later is mixed. Since 2007, only three of the eight who started at least four games as rookies — Nick Foles, Desmond Ridder, and Brock Purdy — started at least eight games the following season, according to CBS Sports. Ridder improved his yards per attempt significantly in his final two rookie starts but was eventually traded to Arizona after being benched twice in Atlanta. Purdy needed no such improvement arc — he was already playing at a high level from his first start and never looked back.

Beck's preseason showed promise in a limited sample: 15 of 19 for 188 yards, one touchdown, no interceptions, according to Sporting News. The regular season, against a defense built to win now, will be a different test entirely.

Why it matters — Beck's performance over eight games will likely determine whether Arizona spends a top-10 draft pick on yet another quarterback next spring — making this debut a potential turning point for the franchise's direction.
