Yorkshire have cancelled the contracts of the three overseas players they were due to employ in 2020.
No cricket will be played in England and Wales until July 1 at the earliest due to the coronavirus pandemic, with the structure of the season beyond that unknown.
South African left arm spinner Keshav Maharaj had agreed to re-join the White Rose for their opening two Specsavers County Championship fixtures against Gloucestershire and Essex.
Later this summer, Yorkshire were set to add yet more international experience to the spin department with India’s Ravichandran Ashwin due to play the majority of the remaining Championship fixtures.
West Indies batsman Nicholas Pooran had agreed a second stint at Emerald Headingley after agreeing to re-join as Yorkshire Vikings’ Vitality Blast overseas player for the 2020 campaign.
However, due to the global Coronavirus outbreak, all parties have come to an agreement to cancel these contracts.
Yorkshire's players are currently on furlough while the pandemic plays out, and Director of Cricket Martyn Moxon said:
Firstly, I really appreciate the players' understanding in this matter. We have been in regular contact with the players and their agents throughout this Covid pandemic.
Maharaj was a big hit for Yorkshire in 2019, taking 38 Championship wickets in five matches.
