Celtics guard Jaylen Brown suffered a concussion after landing on his head following a dunk gone wrong.  Doctor Marv Albert diagnosed the concussion immediately.

Brown didn’t appear to have been knocked completely out and it was good to see him get up and walk off the court on his own.  He later tweeted out that he was ok, but had a headache.

This is exactly why football is so dangerous.  The concussion and CTE virus are starting to spread to other sports.
