Ireland stalwarts Peter O'Mahony and Conor Murray have been included in the Barbarians squad for their match against South Africa in June.
The Munster pair, who retired from international rugby after the Six Nations, won 114 and 125 caps for Ireland, respectively.
Back row forward O'Mahony will retire at the end of this season, while scrum-half Murray will leave Munster to play abroad.
The squad to take on the double World Cup winners also includes former All Blacks captain Sam Cane, who had an on-field run-in with O'Mahony during the second Test of Ireland's 2-1 series win in New Zealand in 2022.
Barbarians head coach Robbie Deans said: "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.
"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 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."
