Hartsville High School will observe a moment of silence on Monday in honor of 18-year-old Ronald Rouse.
Rouse, a 6'3" 335 pound defensive linemen, collapsed on field during Friday night's Hartsville versus Crestwood game.
He was pronounced dead at Carolina Pines Regional Medical Center, according to Darlington Coroner J. Todd Hardee.
Tentative results from an autopsy done Saturday suggest Rouse died of a fatal sudden cardiac arrhythmia brought upon by a congenital enlarged heart, said Hardee. He ruled the manner of death as natural.
Counselors will also be on hand at the high school for any student who wants to talk.
This is standard procedure whenever a student dies, said Darlington County School District spokesperson Audrey Childers.
Hines Funeral Home in Hartsville is arranging Rouse's service. A date and time have not been arranged.
