An east Texas high school football player has died after collapsing on the sidelines during a game.

The Jacksonville Daily Progress reported that Alto high school junior Cam’ron Matthews collapsed on Friday night during a home game against Price-Carlisle, after reaching the bench from a kick-off return seconds before half-time.

He suffered a seizure and doctors, nurses, coaches and trainers worked to keep him breathing.

The rural community is 11 miles from the nearest town. After a 20-minute wait for an ambulance, officials summoned a medical helicopter from Tyler, about 50 miles to the north. Matthews remained in critical condition until he died on Saturday night. No official cause of death had immediately been determined.

Alto high school has an enrollment of almost 200 students.
