Danny Cipriani has accepted an invitation to play for the Barbarians against Australia at Twickenham on November 26.
The former England fly-half will play alongside South Africans Victor Matfield and Bakkies Botha, Wales centre Jamie Roberts, the All Blacks Sonny Bill Williams and Australia's Stirling Mortlock.
The 23-year-old currently plays for Super Rugby side Melbourne Rebels.
England coach Martin Johnson said that Cipriani would not be selected for England while he was playing in the Southern Hemisphere.
