Only 10.6% had not returned to play 6 months postinjury.Discussion This study suggests an overall favorable prognosis for slowly recovering athletes and provides data for athletes and medical teams to consider in calibrating RTP expectations and making decisions about medical disqualification vs ongoing engagement in their sport.BSI=Brief Symptom Index; CARE=Concussion Assessment, Research, and Education; RTP=return to play; SAC=Standardized Assessment of Concussion; SCAT-3=Sport Concussion Assessment Tool–3rd Edition; SRC=sport-related concussion; TBI=traumatic brain injury ER -
