Autopsy results for a South Carolina high school football player who died after collapsing at practice were inconclusive, the Lexington County coroner said, according to The State newspaper.
Lewis Simpkins, a 14-year-old sophomore on the River Bluff football team, was pronounced dead upon arrival at the hospital, coroner Margaret Fisher said.
Fisher said additional studies will be done over the next few days in an effort to identify the cause of death and the investigation is continuing. Fisher said the teen had no prior medical problems that his family was aware of.
Simpkins dropped to the ground during drills Wednesday evening. Two athletic trainers and a coach immediately began CPR and started using a defibrillator on the boy. Paramedics then transported the student to the hospital.
According to the annual report from the National Center for Catastrophic Injury Research at the University of North Carolina, there were seven high school/middle school player deaths from indirect causes during football-related activities or physical exertion in 2015 and 21 in the last three years.
According to the organization, indirect deaths include heat stroke, sudden cardiac arrest or by complications from a non-fatal injury such as infection.
