The Pac-12 men’s basketball tournament in Las Vegas has been canceled after one day of competition because of coronavirus concerns.

Later Thursday, the NCAA announced that the NCAA Tournaments for men’s and women’s basketball also would be canceled, as well as all other remaining winter and spring sports championships as the world continues to grapple with the spread of the virus.

“The Pac-12 Conference has made the decision to cancel the remainder of the Pac-12 Men’s Basketball Tournament and all Pac-12 sport competitions and Pac-12 Championship events, effective immediately, until further notice," the Pac-12 said in a statement Thursday morning. "This decision has been made in consultation with our member universities in an effort to limit the spread of the virus and in the interest of the health and safety of our student-athletes, campus personnel, working and event personnel, and all those who attend Pac-12 events.”

The top-seeded Oregon Ducks and the No. 8 seed Oregon State Beavers had been scheduled to play the first Pac-12 tournament game of the day Thursday in a quarterfinal matchup at T-Mobile Arena. The conference had announced Wednesday night that the tournament would go on, but without fans.

The Pac-12 statement did not address how the conference would award its automatic bid for the NCAA Tournament, but it presumably will go to the Ducks, who won the regular-season title.

Other conferences made similar moves on Thursday morning, one day after the NCAA announced that this year’s men’s and women’s NCAA Tournaments would be played without fans. The Atlantic Coast Conference, Big Ten, Big 12, Southeastern Conference and American Athletic Conference were among the conferences to cancel their tournaments.
