Miley will be checked out by the Cubs' training staff Saturday after his shoulder failed to get loose enough for him to throw Friday, Sahadev Sharma of The Athletic reports.

EDGE Analysis

That no longer seems to be the case thanks to his potential setback. A new timeline for his return should become available after his examination.
