While the finish to the main event of SummerSlam between Randy Orton and Brock Lesnar was definitely planned, the extent of Orton’s injuries and the early stoppage of the match almost certainly were not, and that reportedly led to a confrontation between Brock and respected veteran Chris Jericho immediately after the match. Jericho, who was unaware of the planned finish, was apparently upset with Lesnar for what he saw as Brock taking liberties with Orton, and a combination of miscommunication, adrenaline, and harsh words led to Jericho and Brock having a brief shoving match that was broken up by Triple H and Vince McMahon.
Apparently, both parties settled down immediately afterwards, and Jericho was assured by Orton that everything which had occurred in the ring (other than the unexpected severity of the cut) had been planned ahead of time. There is allegedly no heat on Jericho, who was seen as trying to stand up for another wrestler and honestly mistaken, or on Brock, due to Orton’s injury being seen as an unfortunate accident. Brock flew home from New York immediately after SummerSlam, and is not expected back on WWE TV for some time.
