Seems as though WWE will be bringing NXT UK TakeOver: Dublin in 2021. According to a report by PWInsider, WWE has moved the NXT UK event from October 25th of this year to June 20th, 2021.
This is the second delay of the event due to COVID-19; it was previously scheduled for April 26th before being rescheduled to the October date when the pandemic first began to cause shutdowns.
The event is reportedly still set for the 3Arena in Dublin and would take place at 4pm (local time). WWE has yet to announce this change on WWE.com or social media, and as of now the social media accounts for the 3Arena have also not provided an official update.
