Former WWE star Chris Nowinski recently talked about his work with the Sports Legacy Institute in concussion research, talking with Randy Orton about the issue, his conversations with Chris Benoit and more. Check out the highlights:

On Randy Orton changing his thoughts on the issue: "A guy like Randy Orton just didn't buy into it, and I ran into him in March, and he started talking about his concussion experiences and he was like, 'Gosh I didn't know it was that bad.' He is an advocate for himself now to take time off and so it's interesting to see this turn."

On his conversations with Chris Benoit before his murder-suicide: "We incorporated Sports Legacies ten days before the Benoit tragedy. A year prior to that I sat down with Benoit when I was still working for (WWE) and he just started asking me questions. He was more interested than any other wrestler, which helps me realize that he actually knew there was something wrong with him. He asked me about how many concussions I had and I asked him and he said, 'Well, I had more concussions than I can count.' So, because he told me that and then he told me to give him a call. I remember months later... I called him and he acted like he didn't know why I was calling after he gave me his number. So, I thought maybe there was a memory thing or maybe a mood thing going on. So, when it happened, I was sure that is why it happened."
