Former All Blacks captain Sam Cane has also been called into the squad to face Rassie Erasmus' double World Cup-winning Springboks. Cane and O'Mahony exchanged words during Ireland's series win over the All Blacks in New Zealand three years ago. "We are in the process of finalising a really exciting squad for the match against the Springboks in Cape Town at the end of June," head coach Deans said. "It will be a blend of high-profile global international stars, and other stand-out performers from European clubs, Super Rugby and the Japanese league. "Peter and Conor have been an integral part of the Irish team for nearly 15 years and both have amassed over a hundred caps for their country and represented the British and Irish Lions on a number of tours. "Sam is also a Test centurion, played in the last three Rugby World Cups and captained the All Blacks from 2020-2023. "All three players experience and leadership qualities will be invaluable during the week both on and off the field and I am delighted they have agreed to play for the Barbarians in this historic game."
