2018 NCAA Tournament bracket: Full matchups and seedings on Selection Sunday

Xavier, Kansas, Villanova, and Virginia are the No. 1 seeds in the 2018 NCAA Tournament, which revealed its full bracket Sunday on TBS. The 68-team field is full of surprises as always, so there will surely be a lot to discuss before the First Four games begin in a couple days.

TBS, which broadcast the show for the first time, changed the format a bit this year. The full field of 68 teams was revealed alphabetically at the beginning of the program, then we got to find out who was playing who and what the bracket actually looked like.

The selection committee brought some surprises as usual, so there will surely be some fan bases from bubble teams disappointed by the decisions. Louisville, Saint Mary’s, Notre Dame, and USC are among the teams that were left out of the mix.

Virginia is the No. 1 overall seed for the tournament, while Texas Southern is the No. 68 overall seed.

The 2018 NCAA Tournament begins Tuesday with the First Four games. The first round begins Thursday, and the Final Four is set for March 31 at the Alamodome in San Antonio. The final two teams will play in the national championship game on April 2.
