According to a report by Fightful, Roman Reigns informed WWE Chairman & CEO Vince McMahon that he was cancer free early last week and it was Roman himself who pitched the idea and made the decision to come back on RAW to announce his return. Up until last Monday morning, the only people who were aware of the details of Reigns’ announcement were Vince McMahon, Stephanie McMahon, Triple H, Kevin Dunn & Executive Michelle Wilson.
A separate report notes that after Roman revealed that his cancer was in remission, Seth Rollins joined him at the end of the segment but Dean Ambrose made the decision himself to not accompany his fellow Shield members on stage. Ambrose was reportedly very emotional backstage and so it was quickly decided that instead Reigns & Rollins would save Ambrose after his match later on in the show.
