Andrew Cashner had a setback with his shoulder yesterday and an MRI today confirmed that he did indeed aggravate his original injury.
Cashner has been rehabbing from a mild strain in the back of his rotator cuff originally suffered during his first start of the season back on April 5.
According to Patrick Mooney of CSNChicago.com, the 24-year-old right-hander will now be shut down for the next several weeks before beginning his throwing program from scratch.
While there’s no clear timetable for his return, Cashner is obviously a longshot to contribute before the second half of the season.
