 Like an injury history, Rousey believes would have put a target on her back in the prime of her career. It was just something I always was pushing through. So I would get a concussion and continue to train and I'm hitting the ground over and over again all night taking impacts. And then every time that you got one, it was easier to get another. And that's why I had to leave MMA. I couldn't take a jab without getting a concussion.
