Selection Sunday for the NCAA Tournament is here and teams sweating out the wait until the brackets are revealed got bad news from the Atlantic 10 Conference.

Davidson beat Rhode Island in the A-10 tournament championship game Sunday to steal an at-large bid. Top-seeded and No. 25 Rhode Island looked like a lock to get into the field of 68 no matter what happened Sunday. But Davidson's only hope was to win the conference tournament — and Stephen Curry's alma mater did just that. For bubble teams such as Arizona State, Louisville, Syracuse, Baylor, Marquette and St. Mary's, that's a problem.

Penn won the Ivy League to earn an automatic bid Sunday, and so did Kentucky in the Southeastern Conference.

The bracket unveiling begins at 6 p.m. ET on TBS.
