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.
“I feel real bad for him,” general manager Jim Hendry said. “He worked real hard and his rehab had gone really well up to this point. Obviously the main goal will be to continue to get it right so he can continue to have a bright future. It’s unfortunate.”
While there’s no clear timetable for his return, Cashner is obviously a longshot to contribute before the second half of the season.
