Concussions MUST be taken very seriously. Putting a player back in a game with a concussion, even a mild one, puts them at great risk for life-long disabilities and/or fatal consequences. A concussion must be fully healed before returning to action, and only a trained physician can make that call. Coaches must protect the player from further harm and immediately remove the player from play if any symptoms appear. It is important to note that some symptoms may not appear for 24 hours, so you should take a conservative approach if you witness any head trauma. Likewise, parents must support the decision of the coaches to remove players from games if an injury is suspected.
Parents are encouraged to review the CDC's Heads Up Program for more information.
