As noted, Undertaker was legitimately hospitalized with a severe concussion sustained in his WrestleMania XXX match with Brock Lesnar. Undertaker was released on Monday, however, and was actually backstage at RAW. For whatever reason, the decision was made not to use him on the show.
Those who saw Undertaker backstage at RAW noted that he was limping around pretty badly, and appeared to be in rough shape.
Regarding the decision to end Undertaker’s streak at WrestleMania, there is said to be a number of people in the company who were very unhappy about that decision, but couldn’t — and won’t — say anything about it publicly.
The decision was reportedly made by Vince McMahon, not Undertaker himself. There are conflicting reports regarding the call. Some “in the know” claim that McMahon had to talk Undertaker into it, while others, also “in the know,” say McMahon made the call and Undertaker simply went with it.
