What happened: Kellen Moore confirmed the diagnosis Sunday after the injury occurred during the Saints' padded session. Radunz entered camp on a two-year contract signed in March.
Why it matters: New Orleans must reshape its guard rotation before Week 1 after Radunz made 10 starts at left guard in 2025. The injury compounds a camp in which Bryan Bresee was already lost for 2026 with a torn ACL.
By the numbers: Radunz played 15 games with 10 starts in 2025. A torn ACL limited him to 11 games in 2022 before he returned to start 11 of 16 games in 2023.
What to watch: The Saints' next depth-chart update should show how they will redistribute first-team guard snaps before the preseason continues.
