Sure, it is possible that the opponents of aggressive players have more risk of an injury because they get fouled more, but this is not a real correlation.
I believe this to be true.
I have a player, Matsumoto, who early on in his career fouled out often. I lifted his defense (in particular OD - and he's a big), and that helped considerably - he rarely fouls out now. Additionally, I've never had a player who injures as many players as he does (I *think* current count is 5?).
