Whatever brains he has a concussion can happen from an episode like in this video.
“People are also asking
Can you get a concussion from jarring?
A concussion can result from a fall, sports activities, vehicular accidents, assault, or other direct injury to the skull. A big movement of the brain (called jarring) in any direction can cause a person to lose alertness (become unconscious).”
Sounds like his brain took a pounding….regardless of the cause.
Time for term limits, too.
