Coronavirus: What sporting events have been impacted?

The NBA announced Wednesday that it is suspending the season following tonight's games, after Utah Jazz player Rudy Gobert tested positive for the coronavirus. The NBA said it will use the hiatus to determine next steps.

The NBA season was scheduled to end on April 15.

The sports world continued to be impacted by the coronavirus outbreak, which was declared a pandemic Wednesday.

On Wednesday afternoon, NCAA President Mark Emmert announced that athletic events, including the upcoming men’s and women’s basketball tournaments, will be held without fans.

“The NCAA continues to assess the impact of COVID-19 in consultation with public health officials and our COVID-19 advisory panel,” Emmert said in a statement. “Based on their advice and my discussions with the NCAA Board of Governors, I have made the decision to conduct our upcoming championship events, including the Division I men’s and women’s basketball tournaments, with only essential staff and limited family attendance.”

On Thursday, however, there were announcements that the Big Ten, SEC, Big 12, American Athletic conferences and Atlantic 10 canceled their men's basketball conference tournaments, The Washington Post reported.

Emmert's statement came after Ohio Gov. Mike DeWine said he will issue an order that there would be no spectators allowed at the NCAA First Four games, which will be played in Dayton, WHIO reported.

The announcements capped a hectic day -- and a busy few weeks -- in the sports world.

The biggest question looming is the status of the Tokyo Olympics, which are scheduled to begin in July. So far, Japanese and International Olympic Committee officials have said the Games will proceed as scheduled, but there have been talks about whether competitions should be held without spectators, The New York Times reported. There will be no spectators when the Olympic torch for the Tokyo Games is lit Thursday in Olympia, Greece, the newspaper reported.
