According to F4Wonline, that is not the only change that will be taking place. WWE SmackDown! Live and RAW will not take place in Houston, TX, the same city as the Royal Rumble itself. The live Friday night episode of SmackDown! Live will take place in Dallas, TX and RAW will take place in San Antonio, TX the Monday after the Rumble.
The Worlds Collide (NXT, NXT UK and 205 Live Superstars combined) event will take place at the Toyota Center in Houston.
