A medical examiner has ruled that a 12-year-old boy who collapsed during a football practice in Jacksonville had an abnormal heartbeat and did not die from dehydration.
The Duval County medical examiner's report was released Friday.
It said Rashad Wallace died from a cardiac arrhythmia. The heart might beat slower or faster than usual or beat out of sync.
Wallace died Aug. 2 after collapsing during his Normandy Athletic Association Pee-Wee team's second practice of the season. It was his first year with the association.
The report said cardiomyopathy, a deterioration of the heart muscle, contributed to the boy's irregular heartbeat. There is no indication that heat or dehydration was a cause.
