'March Madness' - arguably the United States' biggest sporting event, along with the Super Bowl - has been cancelled, as the coronavirus impact on American sport escalates.
The men's and women's college basketball national tournaments were due to start next week, but have now followed the demise of the regional conference playoffs abandonned early Friday (NZ time).
"This decision is based on the evolving COVID-19 public health threat, our ability to ensure the vents do not contribute to spread of the pandemic and the impracticality of hosting such events at any time during this academic year, given ongoing decisions by other entities," the National College Athletic Association (NCAA) announced.
Organisers had planned to proceed with the tournaments behind closed doors, but quickly followed suit, when most major US sporting competitions suspended their seasons overnight.
Last year, Tall Blacks centre Jack Salt helped the University of Virginia Cavaliers to the men's title - the first Kiwi to claim that crown.
Several conference tournaments were stopped in mid-flight, with one ending at halftime of a St John's v Creighton Big East quarter-final.

After gathering more information, however, the tour decided to change its position and shut the event down.

The report comes after McLaren withdrew from the opening race of the season, when a team member tested positive for coronavirus.
And a ninth person has reportedly been isolated and tested for the virus at Albert Park.
The coronavirus outbreak, now declared a pandemic, has led to widespread disruption of sporting fixtures.
McLaren chiefs told the Fédération Internationale de l'Automobile (FIA) governing body of their decision to pull out late on Thursday night, 24 hours before practice was due to start in Melbourne.
"The decision has been taken based on a duty of care, not only to McLaren F1 employees and partners, but also to the team's competitors, Formula One fans and wider F1 stakeholders," a McLaren statement said.
"The team member was tested and self-isolated as soon as they started to show symptoms, and will now be treated by local healthcare authorities.
"The team has prepared for this eventuality and has ongoing support in place for its employee, who will now enter a period of quarantine."
Earlier, six-time F1 champion Lewis Hamilton admitted he found it "shocking" that the season-opener was being staged in Melbourne, amid a global coronavirus pandemic.
"I am really very, very surprised that we are here," the Mercedes star said. "For me, it is shocking that we are all sitting in this [press conference] room.
"It seems like the rest of the world is reacting. You see the NBA has been suspended, yet Formula One continues to go on - it's definitely concerning for me."

The announcement came moments after Miami-Dade County said it would suspend the Miami Open and on the heels of Sunday's last-minute cancellation of the Indian Wells tournament in Southern California.

"We have made this decision with everyone's welfare foremost in our minds," said tournament director David Jordan.
"With an evolving situation in the five countries that take part, it is important to make a clear decision in keeping with the advice of the various governments involved."

NHL announces 'pause' on 2019-20 season
Following in the NBA's footsteps, the NHL has decided to suspend its regular season over coronavirus concerns.
The NHL's decision comes less than 24 hours after the NBA suspended its schedule, when its first player tested positive for COVID-19.
At this point, nobody in the NHL has been affected by COVID-19, but many teams share their home arena with NBA teams.
If the NHL is forced to go a step further, and cancel the 2019-20 season and playoffs, it would mark the third time in its history the Stanley Cup hasn’t been awarded.
The Spanish flu forced the cancellation of the 1919 Cup final, while the entire 2004-05 campaign was lost to a lockout.
