The St. Louis County medical examiner has ruled that a 13-year-old football player who collapsed during practice in August died as a result of hypertensive cardiovascular disease — high blood pressure.

Anthony Troupe Jr. was 6-foot-2 and weighed 383 pounds at the time of his death. The medical examiner, Dr. Mary Case, says she couldn't directly link the death to Anthony's size, but obesity is a risk factor. Case also says that death from high blood pressure is uncommon in someone Anthony's age.

Anthony collapsed before he finished running a lap before practice. His father died at age 45 in 2007 due to high blood pressure and clogged arteries.

A phone call on Wednesday seeking comment from Anthony's family was not returned.
