In order to participate in this tournament, all teams must register negative COVID-19 tests for seven consecutive days, per the NCAA's health and safety protocols.

By rule, there will be teams in line to replace any team that would need to drop out due to COVID tests (those teams would have to drop out prior to Tuesday at 6 p.m. If a team has COVID issues following that date, it will result in a no contest/forfeit situation). The four replacement teams in waiting, if necessary, are Louisville, Colorado State, Saint Louis and Ole Miss.

Furthermore, according to the NCAA, teams in conferences that only have one bid (automatic) would be replaced by the runner-up in their respective conference tournaments.
