There are several types of potential causes or reasons for sports injuries: But a lot of sports injuries are most commonly caused by poor training methods and unsafe exercising or training environments.

The most common cause of injury is poor training. Of course injuries can be caused by freak accidents, one-in-a-million type bad plays, practially on the level of fate or chance; but really that is not nearly as common as you might think.

If you attempt to play the game of football at a high level, with other competitors, and you're not 100% mentally or physically in gear, if you're not at peak conditioning, if you're not mentally focused, and the bodies are colliding and flying around? That is a prime time when people might get themselves hurt.

We'll never know, but one has to wonder if maybe the off-field distractions and the crazy lifestyle, maybe had something to do with Junior not being 1000% in peak shape and focused on the practice.... That could certainly cause a bad injury of this sort; in fact it's far more likely that could be a factor, rather than it being pure chance or fate. If one team mate is playing at 100% and the other was partying or distracted or believing his own hype, and only playing at 80% of his potential, which one of them is more likely to get hurt during practice?

Karma sure is a b****. Now which one of you made that voodoo doll?!
