I've been looking around the Web before I decided to make this thread and I've gotten conflicting reports. One has said that when u get knocked out from strikes. No doubt you have suffered a concussion. Basically what defines a concussion is temporary loss of brain function. And a knock out by that definition is loss o brain function. While a few others have said. Not necessarily. You can get knocked out without suffering concussion. Albeit a bit ore rare. But u won't really know until you get evaluated by a doctor. There have been instances where a fighter was knocked out. Went to the doctor and the doctor says he didn't sustain a concussion. So which one is it Sherbros?
