– There’s no official word from WWE on how SmackDown moving back to Thursday nights will affect the international airings. The belief is Canada will also switch back to Thursdays. Some countries like Australia and the UK have been getting SmackDown almost a day early and that may no longer be possible due to timing.
It’s also expected that NXT and Superstars, as well as other first-run WWE Network shows such as a season 2 of Legends House, will also be moved to a new night. Speculation within WWE is that they would be moved to Wednesday.
