Half of H.S. football players wouldn’t report concussion
Of the 120 players who were surveyed, 70% were found to have been educated about concussions and most could identify the signs and symptoms. And even though only half would always or sometimes report their concussion symptoms to their coach, 91 percent admitted that they knew there was a risk of serious injury if they returned to play too soon.
