On Monday, WWE released video footage (see below) of Finn Balor undergoing a special follow-up medical procedure in Birmingham, Alabama last week. Balor, who relinquished the WWE Universal Championship one-night after being the first-ever Superstar to win the title on the post-SummerSlam edition of RAW last month, underwent surgery to repair a badly torn labrum in his shoulder in Birmingham, AL. as well.

The follow-up procedure was handled by Dr. Jeffrey Dugas and involved the use of stem cells, which Dugas noted should help Balor develop more robust tissue in the cartilage defect in his shoulder.

NOTE: The video footage below of Finn Balor’s operation from last week features extremely graphic content.
