PWInsider.com is reporting that Finn Balor suffered a concussion on Raw after he was on the receiving end of a vicious right elbow to the head by Jinder Mahal.
Balor looked to be completely knocked unconscious when he got hit as he fell on the floor face first without protecting himself. Balor eventually recovered and finished the match, winning with his finishing move.
The former WWE Universal champion just made his return after 8 months out on the sidelines and Balor will probably not be cleared to wrestle until he passes the multiple tests needed following a concussion.
The slow-mo replay shows how bad the hit was which you can see below.
