Ireland all-rounder Simi Singh is facing "life-threatening health circumstances" after it was reported he is suffering from acute liver failure and requires a transplant.

Cricket Ireland chief executive Warren Deutrom, who confirmed the situation, described it as "shocking" to learn that 37-year-old Singh was seriously ill, and sent him "best wishes and prayers... as he takes on this new fight".

After feeling unwell in Ireland for some time, Singh returned to his native India for treatment earlier this summer.

The Times of India has reported that Singh is in the Medanta Hospital in Gurgaon awaiting a transplant and that his wife Agamdeep will donate part of her liver.

"The transplant is likely to be performed very soon, and the doctors are positive that the outcome will be in Simi's favour and will give him a new lease of life," the cricketer's father-in-law Parvinder Singh told the Times of India.

Deutrom described Singh as "a central figure within Irish cricket – whether at international, provincial or club level".

"He has shown a desire and drive to succeed," Deutrom added.

"We now hope that this same drive will see him come through the current circumstances. Stay strong, Simi, we're all behind you."

Singh has played 35 one-day internationals for Ireland and made 53 T20 appearances for the country, playing in the 2021 and 2022 T20 World Cup tournaments.
