To the Editor We are writing in response to the excellent article published in a recent issue of JAMA Pediatrics by O’Kane et al.1 The authors’ concern for the risk of concussion among middle-school–aged female soccer players matches that from our own clinical experience and is an important addition to sports medicine literature. The article provides strong support for a relatively high incidence rate of concussion among this population and recognizes a worrisome reluctance to seek medical attention in many injured players.
