Leinster back-row Shane Jennings will captain the Barbarians against Ireland at Thomond Park on Thursday.
Jennings retires from the professional game in the coming weeks after a distinguished career in which he has won 13 caps for Ireland, PRO12 and European Cup titles for Leinster and a Premiership title with Leicester Tigers.
He captains a starting side containing nine different nationalities with 466 international appearances between them.
It includes his Leinster team-mates Zane Kirchner and Jimmy Gopperth with Ulster scrum-half Ruan Pienaar also starting for the famous invitation club celebrating its 125th anniversary this year.
Jennings said: “It’s an honour to lead out such an illustrious team. It’s a great highlight in my career and we’ll be determined to do the Barbarians' jersey justice against Ireland."
Head coach Robbie Deans has assembled a side with a sharp cutting edge containing the likes of Toulon’s leading try scorer David Smith, New Zealand’s Joe Rokocoko and British and Irish Lions wing Alex Cuthbert in the back-line.
Lions tighthead prop Adam Jones anchors a scrum containing a powerful second-row combination in Uruguay’s Rodrigo Capo Ortega and Georgia’s Konstantin Mikautadze.
Japan’s Ryu Koliniasi Holani is a dynamic number eight from Deans’ club side Panasonic Wild Knights.
