Thursday night, the PGA Tour, which conducts the bulk of the professional golf events in North America, announced it was canceling several tournaments and suspending operations until the week of the Masters, which is scheduled for April 9-12.

The meeting includes owners, coaches and general managers, and attracts hundreds of news media members from around the country. The league said in a statement that it would continue “essential business operations” but would consult with experts on new developments.
