It turns out that John Cena wasn’t hurt as much as doctors originally expected. When doctors examined him, they found only a partial tear triceps. This was known when WWE announced Cena’s original recovery time.
There has been talk of Cena still staying out of action until January but with WWE’s thin roster, the decision was made to bring him back. WWE officials knew Cena would be returning 4 or 5 days ago but didn’t decide on the match against Alberto Del Rio until this past weekend.
As of Monday, the current plan for Cena vs. Del Rio for the World Heavyweight Title is to be a regular singles match, not a Hell In a Cell match.
