(KCEN) -- If a player has suffered a head injury, pull them out.
That's the new coach's guideline when one of their players suffers a big blow to the head.
These new rules come from the American Academy of Neurology.
They recommend coaches take players out of the game if they think they've suffered a concussion.
And a player should not be allowed to play again until they've been checked out by a healthcare professional who is well versed in concussion treatment.
Neurologists say the brain can recover more quickly if the athlete rests immediately and are given time to heal.
