SPRINGFIELD, Ill. (AP) -- High school athletes who suffer concussions would need a doctor's approval before resuming play under a measure approved by Illinois lawmakers.
The bill also requires education for coaches, parents, referees and players about concussion warning signs.
The House approved it without any opposition Sunday. It now heads to Gov. Pat Quinn.
Supporters say requiring medical clearance could prevent overeager coaches and players from ignoring the dangers of concussion.
Several states have adopted similar legislation this year. The National Football League supports these laws, as it is currently investigating the effects of concussions on brain development.
The bill encourages recreational leagues to adopt similar standards and training. It does not mandate this action.
