As we previously reported there was a plan in place for The Rock to not only appear at Wrestlemania but to interrupt an Elias concert. The Rock and WWE could not come to terms on the commitment for the show. Unlike some reports have stated, WWE waited until the last moment to call it off.
As of Friday night it was still being discussed however come Saturday night they could not come to an agreement. Sunday morning they changed the plan and inserted Elias into the Cena angle. There is zero hard feelings on both sides and both hoped it could happen. Unfortunately this time it didn't work out however both sides are open and willing to make a future deal.
