The decision to main event WWE Hell In a Cell with Ryback vs. CM Punk for the WWE Title was made on Monday afternoon after John Cena reportedly had another medical examination earlier in the day.
Cena’s right arm had improved significantly over the past week but doctors could not assure WWE officials that Cena would be ready in time for Hell In a Cell. The feeling was they needed two weeks of strong promotion for the main event and because they couldn’t get a solid answer on Cena’s status, the decision was made to go with Ryback.
We noted before that two scripts for Monday’s RAW were created – one building things up to end with John Cena getting the WWE Title shot against CM Punk and the other for Ryback getting the shot. Even after the decision was made to go with Ryback at Hell In a Cell, they still ended up re-writing his script for RAW that night.
