Jackson was placed on the DL on Thursday with a right lat strain, Bruce Miles of The Daily Herald reports.
While it wasn't revealed until Thursday that Jackson is apparently dealing with an injury, his performance on the mound has been less than stellar of late. He allowed seven runs on eight hits Wednesday -- his ninth straight start of allowing at least two earned runs in six or fewer innings. Jackson may have been facing a demotion to the bullpen, but he'll instead hit the DL for a chance to recover and hit the reset button. In a corresponding move, the Cubs recalled Zach Rosscup from Triple-A Iowa.
