For many years, WWE officials have been known to modify or even cancel plans at the last minute before a show. In some cases, they are forced to rework full storylines because of one or more injuries and this was the case before Wrestlemania 34.
The plans for the main WWE show are very often set out several months in advance and then offered to fans in April. In the last edition, two matches were canceled a few months before because of injuries on Monday Night RAW.
At first, Seth Rollins was to be in a single match against Dean Ambrose. Unfortunately, the wrestler was hit at the biceps level in December 2017 and only returned last week. We also learned that Jason Jordan should have been in a program with Kurt Angle in a “father/son” rivalry. Only here, his injury at the neck will have prevented such a clash between the two men.
