Alun Wyn Jones will captain the Barbarians this weekend as they take on a World XV at Twickenham.
This Sunday's star-studded clash will see the famous invitational club take on a selection of rugby's finest players, with Eddie Jones coaching the Barbarians and Steve Hansen taking charge of the World XV.
Former Wales skipper Jones announced his sudden retirement from international rugby last week, just over an hour after Justin Tipuric also hung up his boots at Test level.
