A youth football player who suffered a neck injury in practice has died at a Philadelphia hospital.

Family members say 15-year-old Quadaar White died Tuesday at Children's Hospital of Philadelphia. He'd been injured a week earlier during a football practice in Upper Darby.

White was injured during a Greater 69th Street Wildcats practice last week. Police say White's head struck another player's knee and he wasn't breathing when paramedics arrived.

Family, friends and teammates gathered for a vigil Tuesday night at the field where White was injured on August 24. Members of the cheerleading squad set up a makeshift memorial and Quadaar's sister addressed the crowd that filled the field and spilled onto the street.
