Several states have passed concussion legislation targeting student athletes. Such measures generally require coaches to temporarily remove student-athletes suspected of having a concussion from competition. Those players must have a doctor's note before returning to play.
What's considered acceptable in games and during practice also matters.
"There shouldn’t be any practices where kids are purposely encouraged to hit each other with their heads," says Robert Cantu, MD, author of Concussions and Our Kids . "There are drills used right now… the old-school toughness drills that are just not good."
Cantu also recommends that less contact and hitting be done in practices and scrimmages.
"This kind of attention is going to other sports that also have a high incidence of head injury," Cantu says. "That’s all good."
