Police who were sent to an El Reno home where OU football player Austin Box was unconscious Thursday morning were told he had overdosed, according to a police report.

Box, a 22-year-old linebacker, died after being taken to a hospital, authorities said.

El Reno police said paramedics were sent at 9:30 a.m. to 1219 S Reno Ave. J.T. Cobble, a friend of Box's, called 911 and said Box was unconscious and not breathing. The 911 tape was released by police.

“He takes pain pills, and he's not responding to me,” Cobble said.
