DeSclafani felt discomfort in his side during Friday's rehab start with Low-A Dayton, the Cincinnati Enquirer reports.
According to manager Bryan Price, DeSclafani reported some "sensation" in his side as he got deeper into Friday's outing. The skipper added that the Reds are doing "everything we can to avoid a setback" and "we're not going to push him through it." Those comments would suggest a return next week is unlikely for DeSclafani, but nothing is set in stone at this time.
