injuries: Baseball news for 21 September 2026

The Injuries section tracks player availability across Major League Baseball and international competitions. We report on physiological damage resulting from mechanical trauma during games, including muscle strains and joint dislocations. Updates appear daily after evening fixtures in the United States and Canada. Readers find specific timelines for return-to-play estimates and diagnostic details not listed in standard box scores. This archive covers acute events rather than long-term health trends. We verify each case against team announcements before publication. The focus remains strictly on the mechanics of the harm and its immediate impact on the roster.
