2023 NCAA Division I Men's Basketball Tournament

== Tournament Procedure ==
A total of 68 teams have been entered into the 2022 tournament. A total of 32 automatic bids were awarded to each program that won a conference tournament. The remaining 36 bids were issued "at-large", with selections extended by the NCAA Selection Committee. The Selection Committee also seeded the entire field from 1 to 68.
Eight teams (the four lowest-seeded automatic qualifiers and the four lowest-seeded at-large teams) played in the First Four. The winners of these games advanced to the main bracket of the tournament.
The top four teams outside of the ranking (commonly known as the "first four out" in pre-tournament analyses) acted as standbys in the event a school is forced to withdraw before the start of the tournament due to COVID-19 protocols. Any recipient of an automatic bid would designate a replacement from within their own conference if they need to withdraw. Otherwise, the replacement teams were as follows, in order:
First Four Out 
School 	Conference
Washington State	Pac-12
Marquette 	Big East
Wisconsin 	Big Ten
Iowa State 	Big 12
Once the tournament starts, any team that is forced to withdraw will not be replaced; the bracket will not be reseeded, and the affected team's opponent will automatically advance to the next round.
