The Brewers are starting to get healthy again, and one of the other players they want to get back soon is Zach Davies. Unfortunately, it looks like it won't happen very soon. Adam McCalvy reported this morning that Davies had a setback in his rehab and will not begin his rehab assignment tomorrow. He's currently heading for a MRI to determine the severity of the back injury. We will likely know more in the next few days, but this doesn't look good for Davies' chances to return to the rotation this season.
