The risk of exposure makes them unable to participate in the upcoming games.

There are four preapproved replacement officials available for the March Madness tournament, but two will not be replaced.

This is the first reported COVID-19 case among those who are inside the controlled environment created for the men’s tournament.

Games are set to start this Thursday, March 18.
