Oklahoma State's home opener against Tulsa has been postponed one week.
The game, originally scheduled for Saturday, will now be played on Sept. 19. Kickoff time and television details are pending.
Tulsa said its nine-day pause because of COVID-19 protocols had allowed its team to practice only seven times since Aug. 7.
"Without time to properly prepare physically we would be putting our student-athletes at a greater risk of injury," said Derrick Gragg, Tulsa's athletic director. "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."
OSU said there would be no change for ticket holders other than the new date.
Tulsa coach Philip Montgomery said Monday that canceling the game wasn't an option.
"I think both universities want to play this game," Montgomery said. "It's an important game for the state, in my opinion. This has been a great rivalry. Both these universities have played each other a multitude of times. I think it just makes a ton of sense.
"There wasn't ever any talk of just flat canceling the game. I think both schools and both universities want to play the game. I think the teams want to play the game, so that was never really the discussion. It was just 'Hey, we both have an open date the very next week. It just makes a lot of sense right now that you just postpone it for one week and then we'll play it a week from Saturday.'"
