Oklahoma State fans will wait another week to see the Cowboys take the field. The Cowboys' season opener against Tulsa has been postponed until Sept. 19 because of COVID-19-related disruptions in Tulsa's practices, the schools announced Monday night. Kelly Hines of Tulsa World first reported the news.Tulsa's practice sessions have been limited since Aug. 7 when they started fall camp. The Golden Hurricane had a nine-day pause because of multiple positive tests and was limited to seven practices during their 17-day camp ."The safety and health of our student-athletes is always at the core of all of our discussions and decisions," TU AD Derrick Gragg said in a statement . "Without time to properly prepare physically we would be putting our student-athletes at a greater risk of injury. An open date for both schools presented us with the opportunity to reschedule the game for a week later . I'm appreciative of Mike Holder and Oklahoma State University for their cooperation in coming to this decision."Kickoff time and TV information have not been announced.
