As announced by the promotion originally at one of its shows today and, later, on Twitter:
This is confirmation of an earlier report from talkSPORT's Gorilla Position podcast. No wrestlers have been announced as participating but the Observer notes the big one, Will Ospreay, may not be able to participate thanks to commitments to New Japan.
Zack Sabre Jr. and Marty Scrull are available, however.
This comes just over a week after William Regal announced at an EVOLVE show that other qualifying matches will take place in that promotion.
