OMAHA, Neb. -- The family of an Omaha South High School student-athlete says he collapsed during football practice Tuesday afternoon and died when doctors couldn't revive his heart. 

Drake Geiger's family says the 11th-grader was taken to the emergency room from practice. 

The family has set up a GoFundMe account to assist with expenses. 

Omaha Public Schools said football practices started Monday. The area was in a heat advisory all afternoon and into the evening. The heat index was at 106 the day of Geiger's death. 

The school's principal sent a letter to student and families, saying they had been in touch with the family. 

The principal also says counselors would be available at the school.
