Alex Riley was on the receiving end of a devastating powerbomb into the ring apron at the hands of NXT Champion Kevin Owens following his match with Sami Zayn. The vicious attack left Riley with a back injury that will keep him out of action. The rage-fueled Superstar also revealed on Twitter that he is undergoing surgery next week. The operation will aim to fix the degenerative arthrosis Riley has been dealing with in his right knee.
Though he’s facing a setback in his return to the ring after leaving NXT’s announcing team, Riley remains confident that he will return better than ever on Twitter:
“Surgery booked 4 Thurs with Dr. Andrews thank u to @wwe 4 rushing me in. We can re-build him, we have the technology”
