The prevention and medical management of concussions in sport are advancing, however too many incidents continue to be unreported at the youth level. Participants continue to under-report concussion symptoms during play, putting themselves at risk of further harm and longer recovery. To address this important gap in safe youth sport, we identify the multiple levels of shared responsibility across the sport system that can help reduce the evidence-based barriers to speaking up about injury, and removing young athletes when they are hurt. We present a model illustrating that “it takes a village” to support an environment that promotes concussion symptom disclosure and removal from play, with targeted and integrated responsibilities highlighted across the levels (youth participants themselves; coaches, parents and teammates; clubs, sport governing bodies and safe sport policy makers and educators; society broadly). The article builds on our research and the wealth of concussion safety resources in Canada.
