Singh, 37, has played 35 ODIs and 53 T20Is for Ireland, bowling spin and batting in the lower-middle order. He last turned out for Ireland at the 2022 T20 World Cup in Australia, and his last competitive cricket came a year ago, for Leinster Lightning in the Inter-Pro List A tournament.

"We have received shocking news that our friend Simi Singh is currently dealing with life-threatening health circumstances," a statement signed by Cricket Ireland CEO Warren Deutrom read. "On behalf of Cricket Ireland, and indeed the wider Irish cricket community, I would like to extend our best wishes and prayers to Simi as he takes on this new fight.

"After moving to Ireland, Simi has become a central figure within Irish cricket - whether at international, provincial or club level - he has shown a desire and drive to succeed. We now hope that this same drive will see him come through the current circumstances."

The details of Singh's illness are yet to be confirmed.
