Two Players Championship weekends, European Tour qualifiers and four Challenge Tour events are among the latest raft of postponements due to the Coronavirus pandemic.
The PDC announced on Thursday that several events scheduled for April have been called off but have vowed they will be re-arranged.
The Players Championship double-header in Barnsley from April 4-5, as well as the subsequent European Tour qualifiers on April 6, are the first to be affected.
The Challenge Tour weekend in Wigan from April 10-12, comprised of events 5-8, is also postponed, in addition to the Euro Tour 7 qualifier on April 17 and the subsequent Players Championship weekend.
The rescheduled dates are to be confirmed in due course, with the three postponed European Tour events which had been set for March and April already rearranged for later in the year.
It is expected that all scheduled Unibet Premier League nights in April are to be postponed, with the double-header in Rotterdam having already been rescheduled for September and the night in Newcastle set for October 1.
