Reid-Foley was placed on the 10-day injured list Sunday with a partially torn UCL in his right elbow, Anthony DiComo of MLB.com reports.
Reid-Foley exited Saturday's loss to the Phillies with right elbow discomfort, and he'll now be sidelined for the foreseeable future. Tommy John surgery isn't a certainty but is being considered for the 26-year-old, and he can be considered out indefinitely even if he avoids the procedure.
