That man had reportedly come out to help a neighbor after a tree branch fell.
While he was helping clear the debris, another branch came down, striking the victim in the head.
He was taken to the Hospital of the University of Pennsylvania in critical condition.
The man's name has not been released, but Action News has learned he himself is an emergency room physician.
The view from the Action Cam showed those tree branches still on the ground and the splintered tree standing in the yard.
