The eight-game series between Ireland and Zimbabwe next month will be rescheduled because of Covid-19 quarantine requirements for the Zimbabwe squad.
The matches were to be staged at two venues in Northern Ireland.
It is anticipated the series would be held in August-September 2021, but “some venue changes may be required”.
Three One-Day games were to be followed by five Twenty/20 Internationals from 6th to 24th August.
