DeSclafani (oblique) could start the season on the disabled list, Mark Sheldon of MLB.com reports.
There were thoughts that the right-hander could simply be pushed back to the fifth starter spot in the rotation, but that may not be enough time to get him back to health. The Reds are hopeful that he can go through a throwing progression and throw in a simulated game prior to starting for Cincinnati, so his timetable should become clearer as these points in his rehab process are reached.
