Chase Bisontis’ left-knee injury clouds Cardinals’ rookie plans after preseason incident vs. Raiders

The Arizona Cardinals’ preseason took an immediate turn for the worse when second-round rookie guard Chase Bisontis suffered a left-knee injury during Thursday night’s game against the Las Vegas Raiders. According to Yahoo Sports’ account of the incident, Bisontis was hurt when a Raiders defensive lineman fell into the side of his left knee in the third quarter. Bisontis was then carted to the locker room, ending his night earlier than planned.

For a team in the middle of sorting out its depth chart before the regular season begins, a knee injury to a high-drafted interior lineman is more than a short-term inconvenience. Guards are asked to handle quick-hit blocks, sustain contact, and make frequent adjustments at close range, which means a lower-body injury can affect practice participation and conditioning even if the initial severity is not yet fully described publicly.

The Cardinals selected Bisontis in the second round, indicating the organization’s desire to establish him as a meaningful part of the offensive line rotation. While preseason games do not decide the official roster in the way the regular season does, the value of reps is real, especially for interior players learning timing on pulls, half-slide protections, and run fits. Losing a rookie guard for an extended window can force coaches to lean more heavily on established linemen and lesser-used reserves while the team reassesses who can take the most reliable reps day to day.

The timing of the injury also matters. The third quarter is late enough in the game that teams have often settled into their second-unit matchups, and coaching staffs typically keep an eye on who can execute against live movement and pass rush. With Bisontis removed on a cart, it reduced the chance for Arizona to evaluate him further in that specific run-pass environment, which can leave open questions about continuity across the entire interior over the final stretch of the preseason.

Arizona will now have to balance roster needs with the medical timeline, but no additional details about diagnosis, return timeline, or severity were provided in the Yahoo Sports report. In situations like this, teams often keep information limited until imaging and evaluations are complete, and the next practice and team availability updates are usually the first concrete indicators of how the injury will affect the season outlook.

What to watch next is whether the Cardinals can stabilize their guard rotation and maintain offensive-line cohesion through the remainder of the preseason. For Bisontis, the immediate question becomes availability for upcoming practices and whether the knee responds well to treatment and ramp-up. For Arizona, the larger issue is ensuring that whoever fills in can communicate and execute protections consistently, because the interior line is where small misreads can quickly become big disruptions.
