Blair was removed from Wednesday's start at Triple-A Gwinnett due to a shoulder injury, David O'Brien of the Atlanta Journal-Constitution reports.
Blair was placed on the 7-day DL and will visit Dr. James Andrews on Monday. The right-hander was removed from his outing in the third inning and appeared to sustain the injury while attempting to cover home plate after throwing a wild pitch. Expect an update on his status following Monday's appointment.
