Pittsburgh’s Konnor Griffin is scheduled to begin a rehab assignment after missing nearly a month with a forearm injury, according to Yahoo Sports. The injury has limited his ability to field and throw, keeping him out of regular team action. Both reports indicate that Griffin’s next step is a rehab stint, which is intended to help him return to full activity and assess progress against playing demands. The timing is described as starting on Wednesday in one report, while another notes only that he will begin a rehab assignment. No further details about the length of the rehab, which affiliate team he will join, or whether any additional roster moves are expected are included in the provided summaries. The updates focus on the reason for his absence—forearm-related restrictions on throwing and fielding—and the plan for his return through a rehab process.
