He explained that he is grateful for every chance to wrestle again and that he doesn't want his fans to be underwhelmed."Every time I go into that ring, I want to prove that I still belong. I want to show I can still rile up the crowd and get the fans invested in my matches. Two years ago I took a bad fall and I wondered if I would ever step into a ring again. So now every match I have is like a bonus. That’s why I want to make sure I give the crowd every last penny’s worth this Sunday."The Celtic Warrior has been away from WWE since Clash in Paris 2025, and it remains to be seen what the company has in store for him upon his return.
