The latest NCAA Tournament bracket projections are here. Selection Sunday is upon us, where the March Madness Field of 68 becomes official. Five conference tournament championship games tip off Sunday including potential bid-stealing scenarios for teams on the bubble in the American Athletic, Atlantic 10 and Ivy League.

The SEC fights to top the Big East (2011) for most tournament selections in one season with 12. Nine of the league’s 16 teams are locks, while Vanderbilt, Georgia and Arkansas should be on the cut line. Texas and Oklahoma, on the other hand, could be sweating in a few hours before the final reveal. The winner of Tennessee-Florida in Nashville will assuredly get one of the four coveted No. 1 seeds.

The NCAA Tournament bracket will be revealed in a televised special on CBS Sports on Sunday at 6 p.m. ET.
