Chris Jericho is dealing with an elbow injury at this time. Previous reports stated that no one from The Inner Circle or The Pinnacle suffered any injuries during the Blood and Guts match.
Jericho was going to be pulled off of AEW programming for for 1-2 weeks to sell that big cage bump from the finish to the match. He ended up appearing on AEW TV this week with his left elbow taped up and in a brace.
The Wrestling Observer is reporting this is a legit injury and not a part of the storyline.
The Observer later discussed the injury on Wrestling Observer Live, and said Jericho suffered a legitimate injury in falling off the Blood & Guts cage, possibly a fracture of his elbow.
