The Pac-12 has become the second major conference to shift to a conference-only fall schedule amid growing concerns over the coronavirus pandemic.

The announcement came after a meeting of the Pac-12 CEO Group on Friday and a day after the Big Ten opted to eliminate nonconference games for all fall sports.

Pac-12 Commissioner Larry Scott said in a statement, quote - “The health and safety of our student-athletes and all those connected to Pac-12 sports continues to be our No. 1 priority. Our decisions have and will be guided by science and data, and based upon the trends and indicators over the past days, it has become clear that we need to provide ourselves with maximum flexibility to schedule, and to delay any movement to the next phase of return-to-play activities.”

Two hours later, the Pac-12 announced that Scott had tested positive for COVID-19 and was under self-quarantine.

The Atlantic Coast, Big 12 and Southeastern conferences are still weighing options for fall sports. On Wednesday, the Ivy League became the first Division I conference to suspend all fall sports until at least January, leaving open the possibility of moving some sports to the spring if the pandemic is under better control.

The Pac-12′s decision covers football, men’s and women’s soccer and women’s volleyball. Conference-only schedules will be announced no later than July 31.

The conference is also delaying the start of mandatory athletic activities until a series of health and safety indicators become more positive. Athletes who choose not to participate in the next academic year due to COVID-19 concerns will continue to have their scholarships honored and will remain in good standing with their teams.
