STILLWATER, Okla. (AP) – Oklahoma State basketball player Tyrek Coger died after a 40-minute team workout on the football stadium stairs in hot weather, university officials said Friday.

Coger, a 21-year-old forward who had recently transferred to OSU, did not appear to be struggling during Thursday’s workout at Boone Pickens Stadium, OSU spokesman Gary Shutt said Friday at a news conference. Afterward, Coger sat down and when the team went to check on him, they noticed there were issues.

The team called 911 and paramedics arrived at 5:08 p.m. Coger arrived at Stillwater Medical Center at 5:48 p.m. and was pronounced dead at 6:23 p.m., Shutt said.

The temperature at 5 p.m. Thursday in Stillwater was 99 degrees with a heat index of 105 degrees, The Stillwater NewsPress reported.

Oklahoma State basketball coach Brad Underwood broke down Friday as he remembered Coger, noting that he was in Las Vegas on a recruiting trip when he learned of Coger’s death and that the past two days have been the most difficult of his coaching career.
