The cause of death of an Alabama high school football player who died after collapsing during a practice in August has been revealed, according to the Coffee County Coroner’s Office. 

Semaj Wilkins, a 14-year-old freshman at New Brockton High School, suffered a medical emergency during football practice on Aug. 13. According to the coroner’s report, he collapsed and was “unresponsive” before being taken to an area hospital. 

Semaj tragically died, and on Thursday an autopsy performed by the Alabama Department of Forensic Sciences determined that his cause of death was congestive heart failure due to cardiomegaly with biventricular hypertrophy, resulting from a coronary anomaly.

The death was classified as natural. 

The Mayo Clinic’s website defines cardiomegaly as an enlarged heart, and ventricular hypertrophy as a thickening of the heart walls. The condition can cause the heart to fail to pump blood efficiently.
