There are very few instances in WWE where the company will announce a big match for one of their upcoming pay-per-views and then for whatever reason that match doesn't happen, but it still occurs every now and then.We most recently saw this happen when the Rey Mysterio vs Roman Reigns Hell in a Cell match was taken off of the Hell in a Cell pay-per-view and added to the Friday Night SmackDown go-home show instead.But what I want to look at today is recent instances of a Superstar being announced for a pay-per-view match only to end up getting pulled from that match in the last minute.So without further ado, let's take a look at 5 WWE Superstars who have been pulled from announced pay-per-view matches at the last minute.#5.
