5 PPV matches WWE cancelled in 2018

#3 - John Cena vs Kevin Owens - WWE Super Show Down

This match was later converted into a tag team match

Just like the Greatest Royal Rumble PPV, WWE decided to go all out in their first ever Australian PPV, WWE SuperShow Down. They announced a "Last Time Ever" match between Triple H and the Undertaker for the show and even announced a singles match between John Cena and Kevin Owens for the event.

However, a few days later this singles match was converted into a tag team match as Elias joined hands with Kevin Owens to take on the team of John Cena and Bobby Lashley. The reason behind this change could have been John Cena's fitness issues as the 16-time World Champion only performed his signature moves in the match, something that would not have been possible had that match been a singles' match against Kevin Owens.
