Miley has been shut down for 10 days due to left elbow inflammation, Meghan Montemurro of the Chicago Tribune reports.
Miley was delayed to start camp, but the Cubs claimed that wasn't due to an injury but rather due to the team's program for veterans. As it turns out, he's dealing with an injury after all, as an MRI revealed inflammation after he complained of elbow soreness. He's expected to resume throwing once his 10-day shutdown period is over, but he'll still have to finish his spring build-up at that point, so he'll miss multiple weeks to begin the season even if he avoids further setbacks.
