Recently Finn Balor received a stem cell injection to help with his recovery. Dr. Jefferey Dugas obtained some bone marrow from Balor’s pelvis then injected it into his shoulder to help with Balor’s cartilage defect.
Finn Balor has been out recovering from his shoulder injury (labrum tear) that he suffered during his WWE Universal Championship title match against Seth Rollins during SummerSlam which you can see on the video below.
