Yorkshire have cancelled the contracts of spinners Keshav Maharaj and Ravichandran Ashwin and wicketkeeper-batsman Nicholas Pooran by mutual consent amid the coronavirus pandemic.
On Friday it was revealed the shutdown of cricket in England and Wales would remain until at least 1 July.
Pooran had signed a deal covering “the majority” of the T20 Blast group stage.
“The players have been extremely professional and appreciate the uncertainty facing counties at present,” Yorkshire director of cricket Martyn Moxon said.
“We hope that we will be able to see them at Headingley in the future.”
With ongoing uncertainty of when the 2020 season will start, a number of clubs have taken the decision to abort deals with overseas players.
Wicketkeeper BJ Watling and all-rounders Glenn Maxwell and James Faulkner will not now be joining Lancashire, while Matt Henry (Kent), Nathan Lyon (Hampshire), Michael Neser (Surrey) and Cheteshwar Pujara (Gloucestershire) have also seen their overseas contracts cancelled.
