What should I do if a player may have a concussion?

Follow the CDC HEADS UP steps:

1. Remove the player from play right away if they show any sign or symptom of a concussion after a bump, blow or jolt to the head or body. When in doubt, sit them out.
2. Check for danger signs and call 911 for any of these: seizures, not recognizing people or places, repeated vomiting, increasing confusion or agitation, loss of consciousness or trouble staying awake, slurred speech, weakness or numbness, a worsening headache, or one pupil larger than the other.
3. Tell the parents, and make sure a healthcare provider evaluates the player. Don't try to judge the severity yourself.
4. Keep the player out for the rest of that day and until a healthcare provider clears them to return.

Watch for: looking dazed or confused, forgetting plays or assignments, slow answers, clumsiness, vomiting and mood changes. Players may report headache, dizziness, nausea, vision problems, sensitivity to light or noise, or feeling foggy. Symptoms can appear hours or days later.
