DeSclafani will be shut down for four weeks with a UCL sprain, Zach Buchanan of the Cincinnati Enquirer reports.
DeSclafani was expected to miss his first turn in the rotation to start the season after the sore elbow delayed his spring debut. However, an MRI revealed he is dealing with a sprained UCL and will be shut down for at least four weeks, which ultimately lands him on the DL for Opening Day. It's not ideal news for both parties, but the injury is not considered surgical; it'll be big if the 26-year-old can avoid Tommy John surgery. He'll be reevaluated in a month, but for now, expect the young Cincinnati arms -- Cody Reed, Tim Adleman (shoulder), Amir Garrett and Robert Stephenson -- to compete for the vacated rotation spot.
