Dunn is visiting orthopedic surgeon Dr. David Altchek in New York this week to have his pitching shoulder examined, Mark Sheldon of MLB.com reports.
Dunn was diagnosed with a strained right subscapularis, which is the same rotator cuff muscle that forced him to miss nearly a full calendar year between the summer of 2021 and the summer of 2022. It's unclear when he may be able to throw again.
