Jim Ross updated his blog on Sunday and gave his thoughts on John Cena's right Achilles injury. Below is an excerpt:
WWE.com reporting that WWE Champion John Cena has sustained an injury while on the European Tour. The report states that Cena has issues with his right, Achilles tendon which can be a dicey matter. Achilles injuries can be puzzling especially if they aren't torn and don't require surgery. In other words these types of injuries can linger if one doesn't get the proper rest and allow the tendon to heal. The injury is legit as Cena has been suffering through this matter for several days even though he hasn't missed any bookings. Always said the man has the work ethic and toughness of an offensive lineman which is a good thing.

I don't want to get into playing doctor but from what I've heard regarding Cena's injury, it doesn't sound like a tear. A tear of the Achilles tendon requires almost immediate surgery and 6-9 months of rehabilitation. Kobe Bryant of the Los Angles Lakers recently suffered an Achilles tear and working through it was not an option.
Cena has tried to work through the injury, albeit in pain, and the fact WWE is putting a question mark on his Extreme Rules status (still three weeks away) seems to indicate that time off is going to be warranted.
