From the CDC..."
A concussion is a type of traumatic brain injury—or TBI—caused by a bump, blow, or jolt to the head or by a hit to the body that causes the head and brain to move rapidly back and forth."
That said, there is little doubt that your son's friend would have suffered a significantly greater injury - possibly fatal - if it were not for the helmet absorbing much of the impact force. Sensible people understand that a broken/cracked/dented helmet resulting from an impact means the helmet did its job.
