Under Michigan state law, youth athletes must be removed from play if they are suspected of suffering concussions. The athletes cannot return to play until they are given clearance from a health professional. The reason for this is that concussions are brain injuries, caused by a blow or jolt to the head, and they can result in very serious consequences, particularly when they are not treated promptly. Michigan is among a number of states that have applied concussion laws to youth sports as the nature of head injuries is becoming better understood.
Depending on the severity of a concussion, youth athletes typically sit out of play for one or two weeks. A recent study, however, has found that athletes may actually need to sit out much longer in order to recover from concussions.
