Trey Benson placed on IR with a knee injury — Arizona’s RB depth takes another hit. Here’s the latest on the injury, depth chart moves, fantasy fallout and what’s next.
Trey Benson injury — headline in one sentence
The Arizona Cardinals have placed rookie running back Trey Benson on injured reserve with a knee injury and he’ll miss at least four games, a development that leaves Arizona dangerously thin at the position after James Conner was already shelved with season-ending foot surgery. (ESPN.com)
Trey Benson — the five facts you need to know (fast)
- Trey Benson placed on IR: The Cardinals announced Benson is being placed on injured reserve after sustaining a knee injury. He’s expected to be out a minimum of four weeks.
- Context — Conner already out: James Conner previously underwent surgery and is out for the season; Benson had been thrust into the feature back role.
- Immediate roster moves: Arizona signed veteran RB Michael Carter (and/or Jermar Jefferson per practice-squad moves reported) to help fill the void and shuffled the practice squad. Expect more short-term signings.
- Depth chart re-ordering: With Benson sidelined, the Cardinals’ RB depth chart will lean on Emari Demercado, Bam Knight and newly signed Michael Carter — a major loss of upside and explosiveness.
- Fantasy & matchup impact: Benson’s IR designation creates immediate fantasy churn: his Week-to-week looks are now free-agent fodder (Demercado, Bam Knight, Michael Carter) and matchup managers must pivot. (PFSN)
Those five essentials are the anchor points to understand roster impact, short-term fixes, and where to watch for official updates.
What happened — the immediate chronology
Trey Benson exited Arizona’s previous game after suffering a knee injury late in the contest and subsequently missed practice. Team reporters and national insiders (Adam Schefter among them) confirmed Benson’s status was doubtful for Week 5 and later announced he was being placed on injured reserve, ruling him out for at least four games. The move came as the Cardinals were already coping with the loss of veteran James Conner (foot surgery). Arizona quickly added backfield reinforcements to stabilize the roster, including veteran Michael Carter (and reports of practice-squad addition Jermar Jefferson). (NBC Sports)
The medical specifics released to the public so far describe the injury as a knee issue; the team described the IR timeline as a minimum four-week absence consistent with NFL injured-reserve rules. As with many in-season knee injuries, the exact timetable could change depending on imaging, medical clearance and possibly a conservative rehab timeline.
Why this matters: Cardinals roster & offensive identity
A backfield already on life support
Before Benson’s injury, the Cardinals were already grappling with a major blow: James Conner’s ankle injury required surgery and landed him on IR for the season. That thrust rookie Benson — who had shown flashes and gained meaningful carries early — into the lead role. Benson’s placement on IR removes the team’s primary upside runner and leaves Arizona to find a replacement that can produce chunk plays, pass protection snaps, and durable volume in an NFC West slog. Reuters and the team’s official depth chart show the immediate reordering.
Offensive ramifications
Arizona’s offense under HC Jonathan Gannon and offensive play-caller is structured to use the quarterback (Kyler Murray) creatively while needing a dependable, complementary rushing attack for balance. Losing two top tailbacks in a short span forces schematic adjustments: more committee work (Demercado, Bam Knight, Michael Carter), more shotgun, and perhaps heavier reliance on screen plays, misdirection and short passing to compensate for reduced interior power. Over a full game plan, those changes can both limit red-zone rushing success and increase pressure on the offensive line to hold up for longer third-down conversions.

The depth chart now — who steps up?
Official listing and practical projection
- Before injuries (starter view): James Conner (IR) → Trey Benson (starter) → Emari Demercado → Bam Knight → Michael Carter (practice squad promotion potential).
- After Benson placed on IR: Emari Demercado is likely the immediate lead option for early-down power and special-teams snaps, with Bam Knight as a rotational inside/outside option. The Cardinals already moved to bring up Michael Carter, an experienced NFL back who can play third-down and pass-protect if active. Reports also indicated the signing of Jermar Jefferson to the practice squad as additional depth. Expect a short-term committee; one of those backs could emerge as the new early-down engine.
Practical note: depth charts on paper are helpful, but NFL games are decided by snap share, pass-protection trust and play-call frequency. Emari Demercado has shown third-down utility; Bam Knight is a heavier option in short-yardage packages; Michael Carter’s best value is as a receiving back and situational checker. Cardinals coaches must quickly identify which back can take heavy carries and adjust the run scheme accordingly.
Player profiles — who’s available and realistic expectations
Trey Benson (injured)
Profile & pre-injury role: A rookie with explosive burst and receiving upside who stepped into the role after Conner’s injury. Benson’s early-season carries (and pass-protection snaps) made him an intriguing fantasy and situational starter before the injury. Now on IR, his recovery and rehab timeline become top personnel priorities.
Emari Demercado
What he brings: A tough, every-down grinder with pass-blocking chops and special-teams value. Demercado has been in the mix as a third-down/rotational back; he’s the most obvious in-house candidate to soak up early-down and change-of-pace reps. Expect more early-down snaps and short-yardage calls to go to him in Weeks 5–8.
Bam Knight
What he brings: A physically imposing back useful in short-yardage and goal-line packages — a situational bell-cow alternative for power downs. Knight could be the go-to in short-yardage scripts while Demercado handles more passing-down duties.
Michael Carter (recently signed)
What he brings: A veteran pass-catching back who has experience in committee roles and can step into third-down responsibilities. Carter’s quickness and receiving instincts make him a plug-and-play third-down option if the Cards want to keep Demercado in more between-the-tackles roles. Carter’s signing is a signal that Arizona wants a reliable pass-protector and check-down option on the roster.
Jermar Jefferson (practice-squad/short-term)
What he brings: Depth; can handle rotational snaps and special teams if elevated. He’s not built to be a three-down feature but offers insurance and upside.

Coaching & scheme adjustments to anticipate
With Benson out, expect the Cardinals to:
- Redistribute reps: More committee touches (Demercado/Knight/Carter) with the game-plan tuned to avoid overexposing any single back to injury risk and to exploit matchups (use Carter for third-down speed; Knight for short-yardage).
- Increase pass-game touches for RBs: Short passes to backs, screens, and quick outs will help maintain explosive plays without relying solely on a feature rusher. Michael Carter’s pass-catching skills will be pivotal here.
- Use QB mobility: Kyler Murray’s legs and the designed QB runs might pick up some of the slack, though that increases risk of hits and long-term wear on the QB. Coaches may lean into RPOs and play-action to keep defenses honest.
- Emphasize ball security & pass protection: New or inexperienced lead backs often create mismatches in pass protection; expect game calls to protect the QB and reduce complex blocking assignments until depth proves stable. (Arizona Cardinals)
These are pragmatic reactions that NFL staffs commonly use when a feature back is lost midseason.
Fantasy football consequences & manager advice
Trey Benson’s IR placement immediately changes the fantasy landscape for managers:
- Benson owners: Drop or bench depending on league depth; return timeline is 4+ weeks but may require additional rehab. Monitor the Cardinals’ injury reports and official practice designations.
- Free agents to target: Emari Demercado and Bam Knight become immediate handcuff/flex plays; Michael Carter is a priority add for PPR leagues if he’s active because of his pass-catching competence. Check waiver priority and rostership before making moves.
- Matchup management: Cardinals’ upcoming opponents and their run-defense grades dictate the appetites for rolling the dice on a committee back. Managers should look to stream RBs with favorable matchups while the Arizona rotation sorts out. (PFSN)
Fantasy-specific note: committees compress upside. Unless Demercado or Carter emerges as a clear bell-cow, fantasy owners should pivot toward higher-volume backs available and treat Arizona RBs as TD-dependent flex plays.
Short-term outlook — games 1–4 after the IR move
Over the next four weeks — the minimum IR window — expect the Cardinals to test rotation depth. If one back consistently posts high snap shares and successful rushing yardage (e.g., 60–80+ yards per game and efficient passing-down usage), the coaching staff may coalesce around that player. However, stability often takes time; look for the Cardinals to be conservative early and gradually increase reps for the in-house options. The team may pursue additional veteran RBs via waivers or trades if internal options don’t produce. (Revenge of the Birds)
What the media and analysts are saying
National outlets and beat writers have been consistent: Trey Benson’s knee injury and IR placement is a significant setback for Arizona. ESPN’s Adam Schefter and NFL.com’s Nick Shook reported the IR move and timeline; CBS Sports, Sports Illustrated and Yahoo have run pieces analyzing the depth chart consequences and short-term roster moves. Analysts emphasize that Benson’s absence magnifies the Cardinals’ earlier misfortune with James Conner and places pressure on the coaching staff to find dependable touches.
Longer-term personnel considerations
If Benson’s injury recovery is straightforward and he returns healthy, the Cardinals can regain post-injury backfield continuity. But two midseason back injuries in a row can accelerate roster decisions: Arizona might target a veteran bell-cow back in free agency, lean into the draft next year for a multi-down option, or restructure offensive priorities to protect the QB and open passing opportunities. The long view depends on medical updates, in-game production from the substitute RBs, and the team’s place in the playoff race. (Reuters)
Final thoughts — significance & measured optimism
Trey Benson’s placement on IR is a sharp and immediate blow to Arizona’s rushing ambitions. Losing two backs in close succession forces tactical creativity, fresh roster management and an ability to adapt play-calling so Kyler Murray and the Cardinals offense remain balanced. Yet NFL seasons are long and resilient organizations find stopgap answers — the signing of Michael Carter and the availability of Demercado and Bam Knight give Arizona a path forward. For Benson, the road to return is medical and measured; for Arizona, the next four weeks (minimum) are a test of depth, coaching and front-office agility. (ESPN.com)
