Danny Care is to represent the Barbarians for the first time after being recruited for their Twickenham showdown with Fiji on June 22.
Care announced his international retirement last week having won his 101st cap in the recent Six Nations, becoming England’s sixth Test centurion.
The dynamic 37-year-old scrum-half has yet to agree a new contract with Harlequins for next season but he will be guaranteed at least one more appearance at Twickenham.
Care said: “You don’t get too many firsts at this stage of your career, but this has been a long time coming!
“It’s nearly happened a few times over the last few years, but now the stars have aligned and I cannot wait to finally wear that famous black and white shirt.
“I’ve always watched the BaaBaas with such affection because of their style and how the team approaches the game.
“I feel like the Barbarians and myself could be a match made in heaven, so I really can’t wait to throw my own bit of flair into an already incredible team.”
England internationals Ben Youngs, Zach Mercer and Jonathan Joseph have already been enlisted for the Fiji showdown, which takes place after Wales’ showdown with South Africa at the same venue.
