To reiterate on Parker and Wilson: My wife is a Neurologist Nurse and she said the National Football League has to evaluate 3 steps to be cleared. #1 no lingering headaches, #2 testing (basic thinking and movements), and finally an Neuro Examiner will test them on all 3 phases (plus an MRI or Brain Scan) 1 day before being cleared they must pass all 3. So tomorrow, if they pass, they will be allowed to play, and cleared medically. Any setbacks or a failed test and they will not. She told me concussions are very tricky some more than others. When a person has a concussion the brain hits the skull inside causing it to bruise inside. If they have a MRI or Brain Scan it will show. On DeVante Parker's the hit was a solid side blow with no support of hands to stop it, it was on the right side of his helmet causing a cobweb effect and blackness when he got up that's why he was shaking his head. On Wilson's it was crown hit. These type of hits will make you feel high and you lose slight vision. Since both have participated in practice all week and are physically moving around their odds are very good. My wife told me sometimes they are mild and some so severe with massive migraine headaches and blurriness it takes time for the brain to heal inside because a bruise is actually bleeding without escaping the body. So the NFL Protocol is proper but, it is also scary to put a player or a person back on the job until they are 110%. Question: Would go back to your job if you were not ready to go? Sometimes the NFL should really examine the things they do. It is a risk to play in any sport. Head injuries do occur and it can kill you if you have too many.
