Yorkshire's overseas signings for this year's English county season will not be available after the contracts of Ravichandran Ashwin, Keshav Maharaj and Nicholas Pooran were terminated by mutual consent.
The decision has been taken in light of the coronavirus pandemic, which has already caused professional cricket in England and Wales to be delayed to July 1.
With travel restrictions to the United Kingdom expected to last for an extended period, Yorkshire have come to the conclusion that it is unreasonable to employ foreign cricketers this summer.
Ashwin was contracted to play a majority of the County Championship, having been confined to the conventional red-ball format in international cricket.
South African left-arm spinner Maharaj was meant to perform bowling duties for a couple of games in the Championship campaign whereas the hard-hitting Pooran was set for a stint in the T20 Blast.
Yorkshire's announcement to lay off their overseas players comes in the aftermath of similar statements from Hampshire, Essex and Lancashire.
"I really appreciate the players' understanding in this matter," Yorkshire's director of cricket Martyn Moxon said.
"We have been in regular contact with the players and their agents throughout this COVID-19 pandemic.
"They have been extremely professional and appreciate the uncertainty facing counties at present. We hope that we will be able to see them at Emerald Headingley in the future."
A truncated English domestic season has cast doubts over the feasibility of holding all scheduled tournaments in due course and the possibility of a heavily compressed international calendar.
