If symptoms disappear after 15 minutes, the player can return to action. But if he or she suffers another such concussion, a doctor might restrict activity for a week. A player is confused but does not lose consciousness. Feelings of being dazed or dizzy last 15 minutes or more. The player is taken from the field, examined right away, and checked more extensively than after a grade 1 concussion.
Players can return when their symptoms have been gone for a week.
If the player sustains this concussion after having a grade 1 concussion in the same game, the advice is usually to sit out until symptoms have been gone for two weeks. The player is taken from the field, examined right away, and stays out of action until going a week without concussion symptoms. Extended unconsciousness means a player should be sidelined until going two weeks without experiencing concussion symptoms. Players showing nerve problems or lasting unconsciousness need to be sent to the hospital by ambulance. Suffering two grade 3 concussions means that a player should avoid competition for a month.
