An Oklahoma State spokesman says that the basketball player who died had finished a team workout on the football stadium stairs just before medical issues cropped up.

OSU spokesman Gary Shutt said Friday at a news conference that Tyrek Coger did not appear to be struggling during Thursday's workout at Boone Pickens Stadium, but sat down after and the team went to check on him and noticed there were issues. Shutt said 911 was called and paramedics arrived at 5:08 p.m.

The 21-year-old forward who had recently transferred arrived at Stillwater Medical Center at 5:48 p.m. and was pronounced dead at 6:23 p.m.

Shutt also said that under NCAA rules, basketball teams can meet for eight hours a week during the summer. That time can be broken up as two hours on the count and six on strength and conditioning, or all eight on strength and conditioning.

Oklahoma State says junior college transfer Tyrek Coger has died after collapsing following a basketball team workout.

The school said Thursday that the 21-year-old forward was pronounced dead at Stillwater Medical Center. Oklahoma State plans to release more details Friday about the death. The Stillwater NewsPress reports (http://bit.ly/29R36QY ) that emergency crews responded to a heat exhaustion call at Boone Pickens Stadium on Thursday.

Coger, from Raleigh, North Carolina, played last season for Cape Fear Community College in Wilmington, North Carolina. The 6-foot-8 player had initially signed with Ole Miss last fall but opted for Oklahoma State after the Southeastern Conference ruled he was ineligible because of rules on junior college transfers.

Cowboys coach Brad Underwood says Coger's death is ''like losing a member of the family.''
