The Dublin-based Euro T20 Slam cricket tournament has been postponed for the second year running due to uncertainty caused by the Covid-19 pandemic.

The competition, involving six city franchises based in Ireland (Belfast Titans and Dublin Chiefs), Scotland (Edinburgh Rocks and Glasgow Giants), and the Netherlands (Amsterdam Knights and Rotterdam Rhinos), was originally due to start in 2019 but was postponed shortly before its start date.

The six-match series would have seen sides play each other twice, with all games to be held in Malahide.

Twenty20 stars, including New Zealand's Martin Guptill, Pakistan's Shahid Afridi and England's Dublin-born World Cup-winning skipper Eoin Morgan, who was going to feature with Dublin Chiefs, had all been lined up to play.

Organisers said talks in recent weeks had given a "glimmer of hope" that the competition could be launched this year.

But they said in a statement issued on Wednesday that "continued uncertainty around the impacts of Covid-19 on international travel, quarantine requirements and the status of fan attendance at matches has scuppered plans for the current season".

Cricket Ireland chief executive Warren Deutrom said: "The Slam board reluctantly reached the conclusion that the uncertainty caused by the pandemic and compromises being made to the original objectives did not make it a viable start in 2020."

He stressed the continuing commitment to the competition.

"Even if it takes until the third time of asking, we still very much believe in the viability, purpose and interest in a European T20 franchise concept, and will continue to do our best to bring it to fruition," he said.
