Update: High School Football Player Died From Heart Condition

Update: A South Carolina high school football player died as a result of a sudden irregular heartbeat brought on because he was born with an enlarged heart, a coroner says

Darlington County Coroner J. Todd Hardee said after an autopsy Saturday that 18-year-old Ronald Rouse died of natural causes, WSPA reports.

Rouse collapsed twice Friday night during a football game, and later died at a hospital.

Original story: A lineman for the Hartsville High School Red Foxes collapsed and died Friday night during a football game against Crestwood in Sumter, WLTX reports.

Ronald Rouse, a 6-foot-3, 320-pound senior offensive lineman, collapsed once on the field and again on the sidelines. Coaches and medical personnel gave him CPR and shocked him with a defibrilator before he was taken to the hospital, WISTV reports.

The game ended early after it was announced that Rouse had died.

A Facebook post from the school said that Friday's game was homecoming for the school.

A large crowd, including team members still in uniform, gathered later outside the emergency room at Carolina Pines Medical Center and consoled one another as they waited to express their grief to Rouse's family.

Mayor Mel Pennington, who ordered flags be flown at half-mast, urged residents "to take a moment and ask God to be with this family, to help them find peace in this chaos, and to help this team deal with the grief and shock of losing a brother."

As news of Rouse's death spread, many friends and teammates honored Rouse on social media.

A Facebook fan page was set up in remembrance of Rouse; it had nearly 5,700 fans by early Saturday morning. Meanwhile, hundreds of others tweeted about Rouse.

Darlington County Coroner J. Todd Hardee said in a statement late Friday that an autopsy will be conducted Saturday to determine the cause of death, though one newspaper tweeted that Rouse died as a result of cardiac arrest.
