(CNN) - New safety rules may let parents of young football players rest a little easier.

Pop Warner is making changes, hoping to reduce devastating head injuries. The youth football organization's new rules include limiting contact drills during practice to no more than 40 minutes. The organization is also banning head-on blocking or tackling drills, when players start from more than three yards apart from each other. The chairman of the organization's medical advisory board says he hopes the changes will cut the number of hits to young football players' heads in half.
