The incident took place in the 2016 SummerSlam, where Brock Lesnar locked horns with Randy Orton.
Jericho didn't know that this was planned and was not happy with the way the match ended.
Jericho added by saying that elbows to the side of the head can kill you, if you get hit hard enough in the temple you can die.
He mentioned that he stood up against Lesnar and was about to bite his nose off.
There are not many stars in the company who would dare to stand up against this giant beast. So credit must be given to Jericho for standing up for Randy Orton.
