It might not be the last. Shortly after the Big Ten’s announcement, the Pac-12 announced it would hold a news conference at 4:30 p.m. EDT to discuss the outcome of Tuesday’s meeting with the conference’s university presidents.

Earlier Tuesday, the SEC’s commissioner Greg Sankey said their medical team had cleared the conference to play, but stopped short of confirming the powerhouse conference would, in fact, play.

The Big Ten’s announcement comes six days after the conference that includes historic programs such as Ohio State, Michigan, Nebraska and Penn State had released a revised conference-only football schedule that it hoped would help it navigate a fall season with potential COVID-19 disruptions.

Instead, all fall sports in the Big Ten have been called off and a spring season will be explored.

The decision was monumental but not a surprise. Speculation has run rampant for several days that the Big Ten was moving toward this decision. On Monday, coaches throughout the conference tried to push back the tide, publicly pleading for more time and threatening to look elsewhere for games this fall.

“The mental and physical health and welfare of our student-athletes has been at the center of every decision we have made regarding the ability to proceed forward,” Big Ten Commissioner Kevin Warren said in a statement. “As time progressed and after hours of discussion with our Big Ten Task Force for Emerging Infectious Diseases and the Big Ten Sports Medicine Committee, it became abundantly clear that there was too much uncertainty regarding potential medical risks to allow our student-athletes to compete this fall.”

Warren took over as commissioner from Jim Delany at the start of this year. A former longtime executive in the NFL, Warren walked into an unprecedented problem for college sports.

During an interview on the Big Ten Network, Warren was pressed on whether the decision was unanimous across the conferences and if Big Ten teams could still try to play a fall season, as some coaches suggested Monday.

Warren declined to answer.

“We are very disappointed in the decision by the Big Ten Conference to postpone the fall football season, as we have been and continue to be ready to play,” University of Nebraska leadership said in a statement.

Ohio State athletic director Gene Smith said the Buckeyes would have preferred to play.

“I wish we would have had a little more time to evaluate,” Smith told Big Ten Network.

Over the last month, conferences have been reworking schedules in the hopes of being able to buy some time and play a season. The Big Ten was the first to go to conference-only play, doing it in early July.

The Pac-12 followed two days later and eventually all the Power Five conferences switched to either all conference play or mostly.

The first FBS conference to pull the plug on a fall season was the Mid-American Conference on Saturday, and then the Mountain West did the same on Monday.

But those conferences don’t have the revenue, reach and history of the Big Ten, which seemed positioned to pour resources into trying to protect their athletes from getting and spreading COVID-19.

The Big Ten touts itself as the oldest college athletic conference in the country, dating back to 1896 when it was called the Western Conference, and its schools have been playing football ever since. It became the Big Ten in 1918 and grew into a football powerhouse.

The 14 Big Ten schools span from Maryland and Rutgers on the East Coast to Iowa and Nebraska out west. Not only has it been one of the most successful conferences on the field but off the field it has become one of the wealthiest.

The Big Ten, with its lucrative television network, distributes about $50 million per year to its members.
