Concussions in the UFC
There has been a lot of news/talk about concussions in hockey lately, and some pressure on the NHL to look into the issue. Some guys have pledged to donate their brains to science to help study it. We all know what has happened to some guys in boxing after decades of taking shots to the head. Does this have any implications in MMA? Does the UFC have any responsibility to look into studying any long term effects of head shots, or is that none of their concern? How many concussions actually happen in the UFC? Basically I'm wondering if you guys think this has any relevancy in the UFC (or MMA in general).
