The testing was following the return from a break Riley gave the team on Aug. 8, allowing the players to go home after it became evident that Oklahoma’s scheduled Aug. 29 season opener would be pushed back into September and amid the uncertainty that surrounded the future of the college football season last weekend.

“Disappointed about the news, obviously,” Riley said. “We’ve done such a tremendous job really this entire time. Certainly, you know when you give your players some time, there is risk in that.”

In addition to the nine positives, Riley said “a relatively small number” are also being isolated because of contact tracing. He said the program had been able to trace back every one of the positives to “community-based infections.” He said when he gave the team time off, “over 75% of our team didn’t leave Norman.”
