“There was no sign of external injury in this tragic, unexpected death. We will be looking closely at possible cardiac causes, given what is known about sudden death in young athletes, but it’s too early to draw any conclusions,” Chester County coroner Dr. Christina Vandepol said in a statement.

West Catholic High School sent parents a letter Wednesday, that reads in part: “We recognize that this moment is a difficult one for our school community. We will have grievance counselors available tomorrow, July 15 … Please keep Ivan’s family, the West Catholic Prep football team and the entire school community in your prayers.”

Ivan’s father tells CBS3 his son loved football and his family. He had three sisters and two brothers.
