No professional cricket will be played before May 28 - leading to the ECB delaying the release of tickets for their flagship competition
The Hundred could be postponed until 2021 if season is squeezed into two months
Tickets for The Hundred have been held back from general sale amid further uncertainty over when the professional season will commence.
No cricket will be played before May 28 due to the coronavirus pandemic, with the ECB building a series of contingency plans.
England's international schedule, the T20 Blast and The Hundred are likely to take precedent in any revised schedule, but it remains to be seen whether any matches are possible.
In January, tickets for the inaugural edition of the 100-ball competition were released to county members.
The following month saw a priority window open for registered fans. Sales broke the 100,000 barrier and Finals Day at Lord's sold out.
Supporters who had signed up were due to offered a second opportunity to buy tickets from April 2, with remaining passes going on general sale from April 8.
Cricket season delayed until at least May 28 as ECB consider options for 2020 campaign
However, both sales have been put back indefinitely as the ECB continues to discuss how the season will be structured. The Hundred is due to kick-off on July 17 with the women's competition starting on July 22.
"In the midst of an epidemic which is affecting the nation in unprecedented ways, it would be wholly inappropriate for us to promote and sell tickets to The Hundred," The Hundred managing director Sanjay Patel.
"We appreciate this may cause some disappointment to fans that were keen to purchase tickets in the April sales window, accessing early bird prices and securing tickets to the most in-demand games.
"When it is appropriate to go back on sale, we will, of course, offer the same ticket offers and accessible pricing. Like the rest of the nation, we all hope that it is not far away before cricket returns to our screens, stadiums, parks and clubs."
