I think it happened not only to Cena, but Batista as well at one point.
Orton's shoulder was already hurt prior to that accident at the gym. Wish he would've been more careful.
Yea that's the thing, whenever ligaments are just as is... it doesn't even have to be heavy weights in order to get hurt, sometimes it just happens over time. I've popped my bicep on a 20lbs dumbbell after over training like a young idiot I was back in the day.
