Bridwell was placed on the disabled list with a left rib injury, Rich Dubroff of CSN Mid-Atlantic reports.
It's unclear when he sustained the injury or how severe it is, but it comes at a time where he was struggling a bit in the Double-A rotation. The 24-year-old held a 5.13 ERA and 4.5 K/9, leaving much to be desired. It's unclear how much time he'll miss, but things should become clearer once he's able to begin throwing again.
