The Arizona Cardinals report a serious injury to rookie offensive lineman Chase Bisontis during their preseason game against the Las Vegas Raiders. Multiple accounts say Bisontis goes down in the third quarter after injuring his left knee and is seen holding the back of the knee as he is treated.

The Oregonian describes the injury as “serious” and ties it to Bisontis’s status as a highly regarded rookie, noting he was selected in the second round of the 2026 NFL Draft. Yahoo Sports reports the injury occurred during the game and attributes on-scene details to ESPN’s Josh Weinfuss. While the sources agree on the player, opponent, and the left-knee injury, they offer limited information beyond the initial injury description, with no shared update on the diagnosis or expected timetable.
