"Unfortunately, whilst out in Sydney for our T20 World Cup prep camp, Craig experienced a recurrence of a chronic issue which we have been managing for quite some time," Mark Rausa, Cricket Ireland's head of physiotherapy, said.

"Whilst we thought we were on top of the issue, it sadly flared up once we arrived in Sydney and began training. Craig will now return home for an assessment with our medical specialists to plan out his rehab."

Ireland will also play two warm-up games - against Namibia on October 11 and Sri Lanka on October 13 - in Melbourne. They will depart for Melbourne on October 9.
