Derek Carr practiced today.

To my knowledge I’ve never had a concussion so is more of a question

What would be the affects of a mild concussion 3-4 days later in terms of a practice ?

We have seen some players be concussed and go to wrong huddle others no sign on field of a concussion but have their helmet taken

A rib injury seems would affect throws a few days later not sure about a concussion of what I’d guess is mild though not sure if there is such as Mild and how ones is tested
I’ve been dealing with post concussion syndrome for a year and a half. After talking to many doctors, etc. I’ve come to the conclusion that all concussions are not created equally and vary person to person. Some people can quickly recover from a severe blow, while others could potentially die from what appears to be a benign blow. I’ve questioned players who took a long time to come back, or didn’t at all, after a concussion. Now my heart goes out to them. It can be a horrible, confusing, debilitating experience.
