The motivation behind the bill is the increasing number of head injuries in youth sports.
Lynch is signing the law Monday.
Under the law, which takes effect Aug. 17, information about concussions would be distributed to all youth athletes each year, and parents would have to sign forms indicating they had read the information before the start of practice.
Concussions are caused by a blow that forces the head to move violently. They can affect memory, judgment, reflexes, speech, balance and muscle coordination. The symptoms become worse if not properly treated. Young people are more susceptible to long-term repercussions than adults.
