The Medical Examiner says an enlarged heart killed Taji Tyrek Coger, who collapsed during a team workout at Boone Pickens Stadium last summer.
Coger and his teammates were running the stairs at the stadium on July 21, 2016. According to OSU, he finished the workout and sat down, then collapsed.
Coger was from North Carolina. He had transferred from a junior college and had been on campus for only 17 days.
In its final report on his death, the ME's office said the cause of death was cardiomegaly with left ventricular hypertrophy. It also said hydrocephalus was a contributing factor. Hydrocephalus is cerebrospinal fluid that surrounds the brain and spinal column.
The report also said the ME found no drugs or alcohol in his system.
