ACC leaders were expected to meet Monday night to discuss possible expansion opportunities, but that has been postponed.

According to The Athletic’s Nicole Auerbach, the postponement is due to North Carolina’s active shooter situation on Monday.

The campus was under a “shelter-in-place” order for much of the afternoon.

Shortly after 4 p.m. ET on Monday, campus police gave the all-clear:

The ACC has reportedly been considering adding a trio of new programs to the conference for the 2024 season: Stanford, Cal and SMU.

Stanford and Cal have agreed to take partial media rights payouts in order to join the league, per multiple reports. Similarly, SMU could forego a revenue distribution entirely for a period of time. According to Yahoo!’s Ross Dellenger, the ACC could add up to $72 million in annual revenue by adding Stanford, Cal and SMU to the conference.

The ACC has yet to take a formal vote on adding the 3 programs, but that could happen this week. Clemson, Florida State, North Carolina and NC State previously opposed expansion when an informal poll was taken earlier this month.

For the ACC to expand, at least 12 of the league’s 15 members (including Notre Dame) would need to approve the move.
