Concussion Safety

Concussion Awareness

A concussion is a brain injury that cannot be seen on X-rays, CT scans or MRI scans. It may affect the way a person thinks, feels and acts.

A concussion may result from a blow to the head, face or neck, or from an impact elsewhere on the body that causes a sudden jarring of the head. A person does not need to lose consciousness to have a concussion. Signs or symptoms may appear immediately or may be delayed.

Possible Signs and Symptoms

  • Headache or pressure in the head
  • Dizziness, nausea or vomiting
  • Blurred or fuzzy vision
  • Sensitivity to light or sound
  • Balance or coordination problems
  • Difficulty concentrating or remembering
  • Feeling slowed down, tired, low in energy or “not right”
  • Changes in sleep or increased emotional symptoms

If a Concussion Is Suspected

  1. Remove the participant from all participation immediately, including warm-up, practice and competition.
  2. Do not permit the participant to return to the same activity.
  3. If a severe head, neck or spinal injury is suspected, call an ambulance immediately.
  4. Arrange medical assessment as soon as possible by a medical doctor or nurse practitioner.
  5. Provide the required Medical Assessment Letter to the coach or Safety Person.
  6. If a concussion is diagnosed, follow the Hockey-Specific Return-to-Sport Strategy and, where applicable, the Return-to-School Strategy.
  7. Provide a Medical Clearance Letter before returning to full practice and competition.

Reporting and Documentation

Any suspected concussion or significant head impact should be documented and communicated to the participant's parent or guardian and applicable team staff, even if symptoms appear to resolve and the participant returns to normal activities.
