World Cup winner Josh Lewsey will sign off his professional playing career in England when he turns out for the Barbarians against England at Twickenham on May 30.
"It's a real honour to have the opportunity to play for the Barbarians,” Lewsey said.
“In an era of professionalism it is a club that upholds the value of sport at its best and to that end it will be an honour to play for them at the end of my career."
The Barbarians squad also includes the likes of Serge Betsen, Luke McAllister and Martin Corry.
The final game of Lewsey's professional career will be played in Australia when the Barbarians play the Wallabies in Sydney on June 6.
