Chris Robshaw will face England in the Quilter Cup game later this month after he is set to represent Barbarians.
Robshaw had played 66 Tests for the red rose team between 2009 and 2018 and captained them in 43 games including the 2015 World Cup campaign.
The 34-year-old recently played his 300th game for Harlequins during the win over Leicester Tigers last weekend which was set to mark his final appearance in England as he heads to San Diego Legion next year but now gets a chance to face his former team one more time at Twickenham Stadium.
"It is a massive honour and privilege to be able to wear the famous Black and White shirt of the Barbarians and I will do so with great pride.
“It has been a strange season and while I have not been able to play out my Quins career in front of fans, I am so happy I will have a chance to say farewell to England at Twickenham.
“It will be great fun and a great challenge to face up against old team-mates and I can’t wait.
“It’s been a very emotional end to the season and I’m so honoured to have the opportunity to be part of the return of the game to Twickenham and to the international stage.
“Becoming a Barbarian will be a very special moment and a very special memory for 2020.”
