DENVER (AP) -- The nation's most sweeping youth-concussion prevention measure is now law in Colorado.
Gov. John Hickenlooper on Tuesday signed a bill that requires even volunteer Little League and Pop Warner football coaches to take free annual training online to recognize the symptoms of a concussion. The new law also requires coaches to bench players when it's believed they suffered a concussion. They would not be able to return to games or practice unless they have medical clearance.
A dozen other states have adopted training requirements to address youth concussions, but Colorado's new law reaches further than others by requiring training in sports with athletes as young as 11.
