Josh Level, 17, died at Wake Forest Baptist Medical Center after he collapsed during a game at Quality Education Academy in Winston-Salem.
Level was a junior at New Garden Friends School in Greensboro.
David Tomlin, Head of New Garden Friends School, and Darrell Cotton, Head of the Upper School, confirmed the news to FOX8.
New Garden Friends was open Wednesday for students, faculty and staff to gather as a community. Counselors were on site for support.
The Level family tells FOX8 a medical examiner found nothing unusual during a preliminary autopsy that would indicate a reason for the collapse.
No other details about the incident were immediately available.
