Roman Reigns shockingly made the announcement last Monday on Raw that he was suffering from leukemia.
It's not the first time the man has suffered from the disease, as Reigns, real name Joe Anoa'i, put it into remission 11 years ago, but never went public with his battle.
However he decided to tell the world about his ordeal last week in order to try and raise funds and awareness for beating the illness.
The whole wrestling world was shocked, with tweets and well-wishes from across the globe, including from rival promotion New Japan Pro Wrestling.
After Reigns' reveal and an advertisement break, the production team cut to a sombre-looking announcers booth, where Michael Cole, Renee Young and a visibly-upset Corey Graves spoke about what just occurred.
It wasn't made clear whether or not the broadcast team actually knew of the reveal, the shocked reactions made it seem like they didn't.
And the Wrestling Observer Newsletter, via WrestlingInc, have revealed all about what happened backstage at Raw last Monday, and when Vince McMahon initially found out about Reigns' illness.
McMahon reportedly found out about the illness on October 18, four days before the announcement on Raw, hence why Reigns missed the weekend live events, even though there wasn't a reason given.
Whilst Vince wasn't at Raw last week, he was constantly in-touch with Triple H who was running things, and the only other four people who knew what Reigns' promo was about were executives and creative writers.
And Roman's tag partners Dean Ambrose and Seth Rollins had no clue of what was about to happen, the only things they knew is that they were briefed to be waiting in the gorilla position for the Big Dog's promo to finish.
It's also believed that whilst Michael Cole knew about Reigns' vacating the title, he did not know the specifics, hence why he sounded so shocked and sombre.
