Here is a release from the NCAA:
The NCAA Board of Governors has expanded the Association’s Confederate flag policy to prevent any NCAA championship events from being played in states where the symbol has a prominent presence.
The policy previously barred the awarding of sites determined in advance of a championship in states that displayed the Confederate flag. However, if a college or university team earned the right to host a championship game based on its tournament seeding or ranking — considered a nonpredetermined award — the team could host on its college campus or in its home territory.
