The NIT will also be played without fans, per Andy Katz of Turner Sports.

As of Wednesday, there have been 1,000 confirmed cases of COVID-19 within the United States leading to 31 deaths, per CNN.com.

The decision comes after the NCAA advisory panel announced it has recommended against keeping sporting events open to the public as a precaution to limit the spread of the coronavirus.

"We do believe sport events can take place with only essential personnel and limited family attendance, and this protects our players, employees, and fans," the panel's statement added.

The advisory panel was established earlier this month and consists of NCAA Chief Medical Officer Dr. Brian Hainline as well as several other doctors and athlete liaisons.

The decision to keep fans from the arenas follows the steps taken by authorities worldwide to attempt to limit the spread of COVID-19. Several events have also been postponed or canceled around the world.
