The Contra Costa County sheriff's office said Monday that former NFL defensive tackle Chester McGlockton died last November from an enlarged heart.
McGlockton, 42, suffered from left ventricular cardiac hypertrophy, according to his autopsy, said sheriff's spokesman Jimmy Lee, via the Bay Area News Group. The condition causes the thickening of the heart muscle leading to a decrease in the size of the ventricles. It is often associated with high blood pressure.
McGlockton was just starting a career in coaching when he died.
