Reds manager David Bell said Saturday that Greene is confirmed to be dealing with inflammation in his right elbow after an MRI revealed no UCL damage, MLB.com reports.
The Reds received good news on the injury a week ago, but the team and Greene sought more opinions. Three separate doctors have confirmed the diagnosis of inflammation. The right-hander will need at least two weeks for the swelling to subside before he begins a throwing program, so he likely won't be a candidate to return from the 15-day injured list until mid-September in a best-case scenario.
