In a move that poses significant legal implications, the University System of Maryland’s Board of Regents on Friday released findings from a university-commissioned investigation into the heatstroke-related death of offensive lineman Jordan McNair. The 6-foot-5, 325-pound redshirt freshman, who had played high school football at the McDonough School in Owings Mills, Md., died on June 13. The death occurred two weeks after McNair had become ill while running sprints during a team practice held in 80-degree weather. Despite exhibiting multiple symptoms consistent with heatstroke, it would be an hour and seven minutes before Maryland training staff called 911 and an additional half hour before McNair was admitted into a local hospital.
