The Giants placed Austin (knee) on injured reserve Thursday, Patricia Traina of SI.com reports.
After being carted off the field at Tuesday's practice due to an apparent right knee injury, Austin was diagnosed with a torn ACL, ensuring he'll miss the entire 2026 campaign. Odell Beckham, Braxton Berrios (undisclosed), Jalin Hyatt (leg) and Isaiah Hodgins will continue to battle for the last one or two spots at wide receiver on the Giants' active roster.
